There's a brand of tri-ply stainless cookware at William Sonoma that, I think, is beautiful. It's Lagostina (can find on WS' website). Has anyone ever used it? I'd consider it for some bigger items, like pasta pots and large saucepans.
I have never used it myself so I cannot vouch for the quality. To a point I feel the outcome of the food depends on what you do with it. I checked out the website and they seem to have some very nice cookware!!!
