Query: These are the best!

Don't get the teflon ones as these pans do nearly as well and you don't have to worry about scratching. In fact you can clean these pans with Comet, if you want. Positives are the durability and the even heating, and performance. Use them once and you'll think the pans you had been using are junk! The negatives are: These pans are expensive to pick up one at a time. However, Calphalon does have specials, and if you're patient, you will be rewarded. Second, you cannot put these pans in the dishwasher! If you're adverse to hand washing pots and pans, you probably want to go elsewhere.
