I've got a couple of Calphalon pans, a 10 inch and a 12inch. Couldn't tell you which 'edition' but they are department store not professional and look a lot like the ones in the post 2 up. I'm really happy with them - I bought a couple of really expensive non stick pans, but someone always seems to end up using a metal knife or fork and trashing them, so I went cheaper this time, and they work just as well as the more expensive ones (although the bottoms are perma-charred!) had them about 5 years and still doing well.
