The answer

Sage Smart Oven Air Fryer XL — SOV905 / BOV905

Target £250–£300 · pre-owned via idoodirect

28 litres. 2400W. Element iQ, which steers power between elements per function instead of just running a fan — the reason Sage bakes properly and budget boxes don't. Toasts nine slices, roasts a 6kg turkey, takes a 23×33cm pan.

Fourteen functions, and none of them are filler:

It is the only machine on the market that is simultaneously a real oven, a real air fryer, and genuinely multifunctional. It browns hard, which is exactly what pairs with the circulator you already own. And it's built to still be working in ten years, which is the whole basis of the used-S-Class rule.

Why this and not the others

The shortlist, settled

MachineFunctionsCostVerdict
Sage SOV905 XL14£250–300 Buy this. Real oven, real air fryer, premium build, browns hard.
Sage Combi Wave 3-in-13 categories
19 presets
£31–196 Adds a microwave you don't have. But its owner sold one because the grill is its weakest feature, and the air-fry pan holds two portions.
Ninja DT200UK10£55–120 Good oven, cheap. But it's a stopgap, and you don't want a stopgap.
Sage SOV86010£216 No dehydrate, no proof, no slow cook. Costs nearly the XL, does less.
Anova Precision Oven 2.012£1,020+ Sells on sous vide. You own a circulator. Demoted.
HYSapientia 24L10£100–124 New entry-level. Exactly what the S-Class rule says not to buy.
The plan

What to do, and when

TONIGHT19:55

Combi Wave auction — my advice is let it go

You said you'd punt, and it's your call, so the number is £50 delivered, absolute maximum — bid once at 19:54:30, never before.

But the honest recommendation is to pass. It isn't what you want, its grill is poor by its own owners' accounts, it'll need cleaning, and every pound spent tonight is a pound not in the Sage fund. Gemma doesn't want the microwave anyway.

TONIGHT10 minutes

Set the alerts — this is the only job that actually matters

On eBay: saved search for SOV905 and BOV905, notifications on. Then follow the seller idoodirect — they are the Sage-authorised refurbisher and the ones who sold an XL at £279.99 on 13 July.

On idooka.com: back-in-stock alert on the SOV905 XL page. £379.99 with a 12-month warranty when it lands.

WEDNESDAY12:55

Take the £49.12 Ninja — bid to £85 delivered

Having compared every photograph on both cheap listings, this is the clean one: no rust, indoors, all accessories, and photographed running at 200°C. The grease film on it is the easy kind. Best Offer is enabled, so £55–60 offered now very likely ends it before Wednesday and takes it off the board.

Budget a Saturday morning and about £15 of consumables to bring it to spotless — full method below.

LATE NOVBlack Friday

The backstop

If nothing used has appeared by then, Sage discount heavily in November. A new XL with full warranty at £300–330 is a perfectly good outcome and only £30 above the used target.

The cheap Ninjas, compared properly

Which one, and what cleaning it actually needs

I looked at every photograph on both cheap listings. They are not equivalent, and the difference is the kind of dirt — not the amount.

£48.18 Photographed outdoors on garden pebbles. Rust staining across the rear vent slots. Auction-house barcode and adhesive residue on the lid, scratched top. Interior has heavy dark carbonised deposits over the fan cover, back wall and floor. Avoid
The distinction that matters: golden grease film wipes off with a soak and a degreaser. Carbonised black deposit needs abrasion — which Ninja explicitly forbid on these surfaces — and rust on the vents means it's been stored damp. The cheaper machine is the dearer job, and it can't be brought to spotless at all.

Cleaning it to spotless

  • Never use caustic oven cleaner. Oven Pride, Mr Muscle and the like are sodium hydroxide. It etches aluminium, strips non-stick off the trays and basket, and creeps into crevices where it off-gasses next time you heat the oven. This is the single most expensive mistake available here.
  • No wire wool, green scourers, or scrubbing brushes. Ninja's own manual: no abrasive cleaners, scrubbing brushes or chemical cleaners — they will damage the surfaces.
  • Never immerse the main unit. Unplug before you start.
  • Roast tray, oven tray and crumb tray must not go in the dishwasher. Only the air fry basket and wire racks are dishwasher safe, and even those wear faster for it.

The kit

ItemCostWhat it's for
Bicarbonate of soda, large tub£2Made into a paste, it lifts baked grease without abrading. The workhorse.
White vinegar, 5L£3Cuts the bicarb residue and finishes glass streak-free.
Astonish Oven & Cookware Cleaner£2Non-caustic paste. Safe on the trays where bicarb alone won't shift it.
Melamine foam pads (magic erasers) ×6£3Used damp and gently — the only thing that properly clears the inside of the door glass.
Microfibre cloths ×10£5You'll go through more than you expect. Separate ones for degreasing and finishing.
Non-scratch sponges (blue, not green)£2Cavity walls and trays.
Nylon detail brush + cotton buds£3Rack rails, the fan grille, and the vent slots where grease hides.
Plastic scraper (or an old bank card)£0Lifting softened deposits. Never metal.
Stainless steel cleaner/polish£4Exterior only. Brings the lid and door surround back properly.
Nitrile gloves£3Obvious.
Total, buying everything≈£27Realistically £10–15, since you'll have the bicarb, vinegar and cloths.

The method, and how long it takes

StageHands-onWhat you do
1 · Strip and soak
evening before
5 min
+ overnight
Unplug. Remove both wire racks, air fry rack, roast tray and crumb tray. Fill the sink with hot water and washing-up liquid, submerge the lot, leave overnight. This does most of the work while you sleep.
2 · Accessories35 minNon-scratch sponge and Astonish paste on anything the soak didn't lift. Detail brush along the wire welds. Rinse, dry thoroughly — any moisture left on the racks will rust them.
3 · Cavity50 min
+ 30 passive
Bicarb-and-water paste over the walls, roof and floor. Leave 30 minutes. Wipe out with damp microfibre, then a vinegar-damp cloth to neutralise. Cotton buds around the fan grille and the element brackets. Repeat once on stubborn patches — do not be tempted to scrub.
4 · Door glass
the worst bit
25 minInside face carries the heaviest film. Damp melamine pad, light pressure, small circles. Finish with vinegar on microfibre. This is the stage that decides whether it reads as spotless.
5 · Rails, seals, vents20 minNylon brush along the rack rails, cotton buds in the door seal channel and the rear vent slots. This is where a machine looks clean but smells otherwise.
6 · Exterior15 minDegrease the lid and door surround, then stainless polish with the grain. Control panel with a barely damp cloth only.
7 · Burn-off2 min
+ 20 passive
Empty, 200°C, 20 minutes, window open. Clears any residue and any lingering smell of someone else's kitchen. Do this before you cook in it.
Total≈2h 30
+ overnight
Split it: soak Friday night, do stages 2–7 across a Saturday morning. Spotless by lunchtime.
The trade, plainly: two and a half hours plus about £15 of consumables, for a £269.99 oven at £55 delivered. If those hours are worth more to you than £215, buy something clean instead. If a Saturday morning with the radio on is no hardship, this is the best value on the whole page — and it is the only route to a ten-function oven under £60 that ends up genuinely spotless.
Closed off — don't reopen these

Dead ends, with the numbers

  • Importing from China. 2.00% duty plus 20% VAT plus £15 clearance. A £70 oven with £110 air freight lands at £235, unbranded, no UKCA mark, no warranty. You'd also be importing what's already here — HYSapientia is a Chinese brand sold in the UK at £115 with a plug and a warranty.
  • Buying from Europe. Dearer, not cheaper. Euronics €499.99, Elesen €449.99, and Windhorn — Sage's own authorised German service centre — entirely sold out. idooka at £379.99 already beats mainland Europe.
  • John Pye. Hammer plus 25% premium plus VAT on everything means multiply by 1.5. And their returns stock sits on warehouse racking and photographs exactly as grimy as it is. Wrong channel for your condition threshold.
  • Anything described "spares or repair", "E2 fault", or "Dirty/Rusty". Including the £93 Sage whose air-fry element is dead — the one function you're buying it for.
  • Gumtree with courier delivery. Their integrated service caps at 5kg. These ovens are 15–20kg, so the buyer protection is void.
The principle

Why waiting is the right move

You set the rule yourself: a well-kept S-Class beats a new Corsa. The corollary is that you have to be willing to wait for the right S-Class rather than buy three Corsas while you look.

  • You are not without an oven. The gas oven works. This is about reducing its use, not replacing it in an emergency.
  • £55 here and £70 there adds up to the Sage. Two stopgaps this week is most of the deposit on the machine you actually want.
  • You've rejected everything grubby on sight, twice. That's a consistent standard, and it rules out almost the entire sub-£100 used market. Accept that and the answer becomes obvious.
  • The XL demonstrably comes through at £280. That's not hope, it's a sale price from five weeks ago through a named authorised refurbisher.
If you want one thing today: set the two alerts. That's the action that buys the oven. Everything else on this page is a way of not buying the wrong one.
