While flipping channels, I found QVC selling Enameled Cast Iron Dutch Ovens (similar to Le Creuset) at very attractive prices.
QVC is selling a 5 Quart Staub Basix Enameled Cast Iron French Oven with Lid (#K3648) for $49.68 plus $8.22 S&H. Available colors are Blue, Red and Yellow.
QVC is selling a 6 Quart Staub Basix Enameled Cast Iron French Oven with Lid and Trivet (#K5374) for $65.76 plus $9.72 S&H. Available colors are Blue, Green, Navy, Orange, Red and Yellow.
I cannot vouch for the quality of these products but I see that they do have a lifetime guarantee.
I couldn't find a direct URL for these items. To find them, do a search for "Staub Basix Enameled Cast Iron" on QVC's web site.
My sister bought 5 Quart Martha Stewart Enameled Cast Iron Dutch Oven from Kmart for $39 (this product has been discontinued) and loves it. She thinks this Dutch Oven is comparable to her 7 Quart Le Creuset Dutch Oven.
