I've been using the same 2 coated aluminum pots since 2005. One holds 2 cups, and is great when it's just me. One holds 6-7 cups, it's overkill for even two people, takes up a lot of room in my pack, and is somewhat prone to bending.
I'd like something in the 3-4 cup range, about 750 - 1000 milliliters, maybe even as much as 1.4 Liters but only if its very conveniently shaped for the pack (and something that big might nudge me toward titanium). I'd like it to have a lid. I want the lid to stay on the pot when it's in my pack instead of popping off like the lids on my current pots. I'd like it to not bend up too much.
I'll usually use this with an alky stove, sometimes with a canister, probably never with wood.
Cheap is good. It doesn't have to be titanium, though I'm open to it. It certainly doesn't have to be designer yuppie. I'm open to making something or buying a grease pot or whatever.
