Ah, the old Svea 123. My first stove. Colin Fletcher swore by it, and I did, too. Gave me many years of great service. And once you got the hang of it, firing up the thing was a snap.
Now, I have an MSR Wisperlite and, for when I'm in a see-how-little-you-need mood, an ESBIT. Love both. When I was in the Reserves, I used a canteen cup with one of those little stove/stands sold by Brigade Quartermasters, et al, with an Esbit fuel bar. For light and solo, that is the way to go if all you need to do is heat a little water.
