I want a Falk 10.5 qt Copper Casserole, but since I can not afford it, I am searching eBay for Steel Lined Paul Revere Limited Edition, Bicentennial Edition or Signature Editions of Copper Ware. Anybody using these? How thick is the copper? How BIG to they come? Would they compare favorably with Falk cookware or should I just take out a second mortgage on my house and spring for what I want?
