totally agree with Sandy
about non-stick, glass lids, Chinese made, etc. Makes no sense to buy pricey non-stick, however would like to share a good find: in a Denver restaurant supply store we bought a Chinese made Non-stick 10" frying pan made by Winco, Model AFP-10NS, and so far it's holding up and cooks better than any I've used, including daughter's non-stick Calphalon (which got trashed). It's made for commercial use I presume, of good and heavy construction, and best of all only around $28. Highly recommend.
There was tri-ply heavy very high quality cookware as early as late 60s, it was West Bend's preminum brand Luster-Craft, not sold in stores. Very expensive but worth it, and with lifetime warranty. We've been using it for 42 years now, so we got our $$$s worth. Had a pan fall off a hook in a basement cellarway, fell down a flight of stairs, broke the real Bakelite (not thermo-plastic) handle. WB replaced the whole pot, no questions asked. Heavy construction and features "waterless" cooking due to precision fitting lids. Great stuff.
