I have the Calphalon tri-ply and LOVE it. It's heavy enough to be sturdy, but not so heavy it's awkward to handle. Quality is really good - nicely balanced, even pans. If you follow the instructions and heat them up properly with a skim of butter or oil, they are nearly as non-stick as true non-stick. They're easy to clean too - barkeepers friend on everything but the shiny part will easily remove any/all marks your food may make on them.
If you're patient, you can find a lot of the Calphalon pans at TJ Maxx and Ross. I built my entire set without actually buying a "set". Just the other day I found a saute pan that runs $100 at BBB for $40 at TJM
