I have the same question. Most helpful post of the day

I found some for sale at my state fair claimed never to warp. But it was over $100 for a SMALL baking sheet! Iβm gonna need a demonstration at least that it doesnβt warp, not just assuranceβ¦ and even then, whoa
I bet there are great options for cheaper
I'm thinking of trying the USA Pan ones. They are fluted and made in the states. I'm not sure though about the coating they put on the steel. Have you tried them already?
