trying to decide what to buy any insight would be appreciated
I just responded to bob_mcbob's post, which is somewhat like your inquiry. CIA Masters cookware is very nice, but it's made in China. I have one small fry pan of theirs. I have no All Clad Coppercore, but it is copper clad, not steel-lined copper. For the price, I would sooner get Mauviel or Bourgeat Copper, both of which I do use and love. They are heavy, but have more comfortable handles than any of the A-C lines. Also, A-C lids and some of the pans (roasters, stockpots, for ex.) are also made in China.
Not copper clad, just one thin layer of copper.
