I have some non-stick skillets, and the surface is wearing off. Also some black calphalon pots are losing their finish (this isn't supposed to happen!) and I wonder if they are safe to use. I am ready to invest in some new cookware and I need guidance about a brand that will last and not give me these problems again. Should I avoid non-stick completely? What do serious cooks use that's not super-premium priced? Thanks!
