I bought a Food Network cast iron enamel dutch oven. Not being able to afford a Le Creuset, and never having had any experience with one, I thought $100 was a good bargain for the FN pan. Well, after two days (with careful use), the cover was chipped around the edge. I exchanged it for a different one at the store where I bought it. When I got it home and took it out of the box to look at it, I noticed that the enamel isn't covering some spots on the very inside cover, and the overall paint doesn't look "even". Should I exchange it again? Are there other brands besides Le Creuset that are better quality and not too expensive?
