When Kitchenaide came out with their beautiful skillets with the really cool looking stainless handles I just had to have some. I bought the 10" teflon skillet, the 8" teflon skillet and the 8" stainless skillet. They were expensive, the 10" I think I paid $118.00 for. Within a year I returned both the teflon skillets to my store which replaced them immediately, the non-stick was no longer non-stick. Within two years with the replacements I simply tossed them in the dumpster and put them down as a really lousy investment. Beyond the teflon issue I felt the handles were too heavy and when on my electric burners, tilted slightly causing one side of the pan to be hotter than the other. The 8" stainless, seems to have a slightly smaller flat bottom and frankly doesn't get used anymore.
About a year ago my local Fred Meyer started carry a cheaper line of Kitchenaide skillets, I would have passed over them but something made me try one out, and then I bought two more. They are much better to work with but I do notice my 12" is a tiny bit higher in the center, with a straight edge I can't see it but liquids tend to move from the center to the outer edge. Anyway, overall I'd say these are a much better pan, heat more evenly and sit level on my burners.
I am however using teflon less, opting for everything on stainless lined copper or simply stainless clad. I don't know if it's that my cooking has improved more or if I'm just not liking using teflon pans but anymore I seem to only use them for eggs and not much else. Pancakes and even fish which I used to have issues with them sticking to the pan, seem to work much better now on my stainless lined pans.
