Hi Steve,
I use a 12" GSI hard anodized aluminium dutch oven. Been using for a number of years now. Can roast, bake, fry and generally just cook the hell out of stuff. Use it at home and at camp. Weighs in at 6lbs 2 oz, a lot lighter than cast iron ones completely non stick and has a very high "camp cooking envy factor" (CCEF) only rivaled by my Cobb oven.
Will take enough stew to feed around 10 folk... we have to make it hearty though LOL. I will say that I rarely take it for one person day jaunts... use my ancient MSR "backpackers oven" kit for that, ( not been available for a number of years though I think I have a couple spare if you want one... message me if you do).
Also when baking there's a knack as to how much in the way of coals to put above and below, again ask as I think I've a PDF guideline on it I can forward.
You can tell that my mate and I were called the "chuck wagons" in the 4x4 club I was in cant you!

It cost me around £40 when I bought it though I think prices may have gone up since.
Never trust a thin cook.
