I never put my non-stick pans in the dishwasher and I have Calphalon non-stick skillets that are 20 years old and still good.
The dishwasher detergent has a scouring agent that will degrade the surface of non-stick pans and render them useless in just a few years.
The Calphalon-type sets carried at Costco and Sam's Club are virtually identical to the name brand and hold up very well at a fraction of the cost.
Tramontina pans are excellent and also the newer Cuisinart Stainless-Steel Multiclad Pro line has received many rave reviews.
Buy the basic set and add the non-stick skillets in the 8 and 12 inch sizes. And I would add the 4-quart saucepan as I often use both a 3qt and 4qt at the same time.http://www.amazon.com/Cuisinart-Multicl ... B0007IQQN0
The cost is reasonable and except for the non-stick pans, they clean beautifully in the dishwasher.
I volunteer at a local women's shelter and they have these pans in the kitchen, which get heavier use than in most homes and have held up nicely.
