Gourmia 7-Quart Digital Air Fryer

I bought this brand of air fryer from Costco ($39.99) a couple of years ago and it's held up well with moderate use. I believe that Amazon also sells it.

One other note...we use disposable liners when we use the air fryer. It doesn't affect the cooking and keeps the unit clean - so no scrubbing which can erode the teflon.
