I use a Svea 123. It's easy to get gas, just use the hose at a gas station, the stove or fuel bottle being on the ground. There's usually a little fuel trapped in the bend in the hose. The last time I flew with my stove, I had it taken away from me at the airport on the US end. They want you to only take a new stove, never used. Bizarre. Has to be empty, in any case. The stoves with separate gas bottles will be easier to get onto a plane. Gas bottles empty and washed out.
