I need to buy some new pots and pans. I have always used non-stick, but even buying a fairly expensive set last time, they start to fall apart in a few years. What do you recommend? I am willing to try non-stick (it will give me a new excuse for dinner not turning out great!), but I definitely want something that will last a LONG time. My aunt recommends All-Clad; does anyone know if it worth the price? Thanks!
