I have two ovens and love them. Last week on the Copper Stat Cruiser outing I did a peach cobbler that went over well. I have been cooking with dutch ovens for over 10 years and still have a lot to learn.
As far a brands I like -

My only gripe is weight. I have been thinking of something like this to save on weight...
