If your at at all accident prone or just like more robust kit I can't recomend the spun steel bush ovens these folks make enough

I've had the 10 and 15 inchers for a number of years and they are no harder to learn to use than a normal cast dutch oven. Since the ashes/coals are evenly spread out under and over it the supposed better heat spreading capablity of cast iron is irrelevant in actaul use. A inverted pizza tray, the sort with holes in it works fine as a trivet for the 15 incher and another with nuts and bolts to make legs means that you can bake two trays at a time of small stuff.
The lids, which supposedly you can use as frying pans, have really deep rims that means you can both pile up the embers and also stops them blowing off as easily. I have used the lid inverted as bakestones, which works well if they are well greased.
The only downer is getting them to the UK. I was lucky enough to have a mate who lived near the factory at the time who wanted a Mini part so we ended up swapping for them and sent by sea the cost wasn't horrendous.
Hillbilly camping gear also make a similar product but I can't say what their ovens are like since I only have one of their comedy sized frying pans with the folding handle.

The quality of the frying pans very good I can say that, solid, like.
No connection to either company just a happy user.

PS a pair of old welders gauntlets are a very handy thing to have with this sort of oven, as is a dedicated ash shovel, the sort of cheap stamped job your granny had for the hearth but with a wooden extension added, some pound shops still have them.
