I've had a Lodge dutch oven for 8 years, given to me as a gift. It came with a chip (gap?) in the enamel. It still cooks wonderfully, though the enamel is stained after a lot of use. But we use it a lot in my household because it does so well. If you are cost-sensitive, I'd recommend Lodge based on my experience.

For those that mentioned Staub, thank you, I was not aware of that brand until now! Will be researching if I ever need cast iron cookware again.
