I'm interested in purchasing a dutch oven for doing stews, chili, and whatever else I can cook up in there. I'd like to know if anyone has any info on where to purchase one and what size to get. I've looked on the Lodge site and considered a camping oven, but don't know what size. I like the idea of the camping oven because the lid doubles as a griddle when inverted, or at least that's what the description says. Any help would be appreciated.
