I'd suggest you get stainless steel instead of aluminum. Titanium is really light, but expensive. I have a titanium spork that is really cool. The Boy Scout type individual mess kits and a couple of medium binder clips can be used as a good dutch oven if you're careful. Remember all mess kits are pretty thin stock and will get hot and burn food quickly. That's from much BSA Scoutmaster experience. You can't beat Army surplus stuff, all stainless steel, and two can be used together to make a dutch oven, too. A US GI canteen, cup and heater all nest together and make a great setup with the mess kit. FallApart and KameApart are fine, as well as Sportsman's Warehouse, REI, Campmor and many other sporting goods and mountaineering outlets. All have pretty much the same stuff, at varying prices, shop for sales and clearances at end of the season.
That's as far as mess kits go. Stoves are a whole 'nother deal.
