I have the same dilemma.
However I have decided that because I already have a slow cooker, an old Tefal air fryer that just fries (it sings but doesn't dance), and a combi microwave, I don't really need a super Air fryer.
They sounded wonderful at first glance, but they don't do all these things at the same time - ie you can't fry some sausages, heat some vegs and fry some chips all at once (which was the impression I got initially from all the advertising.)
All it seems to be, is a machine that can replace several other machines in one.
So I decided against it.
