Can anyone recommend an air fryer thing?

[NeededANameChangeAnyway]

I'm looking for something to try to make home-made veggie crisps in (beetroot, parsnip etc) but trying to keep them relatively healthy.

I've seen a few air fryers on Amazon but they're expensive - can anyone recommend one before I spend a lot of money on something which isn't that great please?

We have the Duronic one and are very pleased with it. We use it more than the oven now as it does most things.

Thanks - it's a decent price at the moment as well.
