I need help finding the right pans. Here is what is going on. Everytime I buy a pan set within a few months the black coating on the pans starts to come off. I am tired of buying a new set of pans every year. I am looking for a set that is dishwasher safe and preferable non-stick. I have extremely hard water. I have a gas stove. I really only ever use the large pan (stock pot) and frying pans out of the sets. I am willing to spend a little more money if I know they are going to last. I was thinking about the orgreenic set but have read some bad reviews. What would you recommend.
