I always camp with my wife so my kitchen setp is geared for two. During 3 seasons we use a 0.9 L Vargo ti pot and for frozen winter trips we use the 1.3 L Vargo ti pot. They weigh 4 & 5 oz. respectively.
Although I am very happy with them, in retrospect, a Kmart grease pot, with handle removed, would probably be just a serviceable for a lot less money and not significantly different in weight. That would leave some money to lighten up elsewhere.
Then again, ti is cool and so am I, well, as long as I use ti cookware :-)
Seriously though, I use the Caldera cone in 3 season camping and I would not buy a pot that isn't compatible with it.
