I've known about All Clad for along time.  I never thought the cost would justify the quality.  Through the years I've thrown away countless sets of cheaper cookware, tools, etc.  A good friend recommended I buy at least one All Clad copper core and give it a try.  After I tried the one pan.  I bought the 10-piece set.  Completely worth the cost.  I'm an aircraft mechanic.  I work on corporate jets.  If I've learned anything over the years.  It's that quality over quantity is the way to go.  The fit, finish and performance of these pans is beautiful.
