Ooni Karu 16 Multi Fuel Outdoor Pizza Oven - £559.20 delivered @ John Lewis & Partners

I own this model, although I've only used with wood. I think I paid slightly more than this. I'd agree that its expensive for what it is, but it is very good. I've not experienced the inexpensive models but a neighbour bought an aldi or lidl one and was unimpressed with it (this was a year ago, the current lidl model may be better).

You ideally want some thermal mass and an insulated wall above the pizza in addition to the stone. The digital thermometer on the ooni makes it very easy to maintain the correct heat and the pizzas cook in 50-70 seconds at around 500C.

I'm not suggesting it'd be impossible to achieve the same on an £80 model, but it is easy to get consistent results in the ooni.

My other comment would be size- this ooni can make up to 16" pizzas whereas their smaller model takes up to 12" like the Lidl one you reference. I think the majority of pizzas we've made with ours would actually fit in the 12" ovens, so may be worth considering whether you need the larger oven. Its easier to work with because you have more space in the larger oven to turn them, but you sacrifice portability and pay significantly more for it.

If you don't get a model with an inbuilt digital thermometer, I'd recommend getting a of those infrared types.

Sorry mate but that's the ugliest pizza I have seen.

No, you're wrong. The wise and sensible ones will vote cold, and the ignorant will go and buy that oven. (edited)

Which garden centre? Can’t see Lakeland beating this price
