I picked this up for $29.99, and it's beautiful.  In my opinion, Calphalon Tri-Ply is just as good as All-Clad's Stainless line, except it's 3 times cheaper.  With All-Clad, you're getting the same three-layered stainless steel with aluminum disk, but paying hundreds more.  I was considering All-Clad for awhile, but there were two things that changed my mind.  The only possible advantage of All-Clad Stainless over Calphalon Tri-Ply is that it utilizes magnetic steel, which may help if you have an induction cooktop.  Add to that fact that I don't have an induction cooktop, and magnetic steel tends to be of lower quality as well.
