The Mini-Trangia is great! You can take it on a plane, buy fuel anywhere (or if your stuck, burn vodka). It boils water in about 5 minutes depending on the fuel and is light and super compact because the stove, a fry pan, a saucepan and a handle all fit together for storage.
BTW Ricohman, I used to sell those cameras. The rangefinder cameras were the best Ricoh made. Optics were good too, but not quite as good as my Konica Auto S2
