Query: the best 30 bucks i have ever spent

i am a recent convert to calphalon cookware. earlier i cudnt ever figure out why i needed to spend $30 on one piece of cookware alone.but use calphalon once and u can never go back.the calphalon commercial line is awesome. the pan has weight to it it is hard anodized on the exterior and has a nonstick interior coating. the pan heats up really fast and i have seen that it retains heat amazingly well.i have a ceramic cooktop it sits perfectly flat on my burner.clean-up is a breeze with good old dawn and warm water
