Pots & Pans Suggestions Needed

My grandpa generously gave us a large Calphalon pot & pan set for our wedding several years ago.  It was the nice non-stick set that has served us well.  Lately though, I noticed the non-stick finish on my big sauce pan has been flaking off.  Now, I don't necessarily see it flaking, but all along the inside edge I can see right down to the metal.  It's concerning to think of chemical flakes in our food, so we want to buy a new sauce pan.  What type to get though?  Do we go for the steel pan?  Copper?  Try our luck with non-stick again?  If you have any suggestions, please share!
