My standby is the MSR Whisperlight Internationale (about a pound plus fuel). Bombproof and burns any liquid fuel. Two coolest things I found recently are variations on the TLUD: wood gas campstoves, one with a small fan, like the Zip Stove but way more efficient (1.5 lb), and one with natural draft, no moving parts, dead simple and weighs 7 0z. w/o the lids, 9 all packed up/ See the powered one at http://www.woodgascampstove.com/
and the simple one at http://cgi.ebay.com/SURVIVAL-CAMPING-WOO...#ht_1160wt_1141

These will all cook for groups and are overkill (or luxury, depending on your perspective) for solo. I really like that little Esbitt for solo/ultralight.

Wherever you go, there you are.
