Mine was acquired from a colleague three years ago for a tenner (expat...people sell their stuff when they move on, which is excellent for long stayers like me!).
It's a basic, older model with one drawer & I absolutely love it.
When I first bought it I had 3 teenage dc at home & it was super handy for them cooking beige snacks.
It was also a useful bit of kit for family cooking - roasting a chicken to have with salad, or doing chips to go with something on the hob, or garlic bread or samosas etc etc.
I still used my oven quite a bit when cooking for four, but the AF was really useful when only part of the meal needed an oven.
Now down to me & dd2 at home & I'd say I seldom need the oven.
Tomorrow I'm doing roast salmon with tapenade (AF) alongside lemon mash with broccoli steamed over the potatoes. Less faff than panfrying the salmon & quicker than the oven.
Would I buy a fancier model when this one packs up? Probably not. I'd buy another 2nd hand one.
So it might be worth considering how much you want to spend on bells & whistles - but yes, absolutely great piece of kit.
