My all time favorite lighter so far is the Solo Candle Lighter. I like that it extends - makes lighting camp fire setups and stoves sooo much easier. And its easily refillable.

Here is a site that carries it so you can see it, but I'm not sure if I've ever purchased from this particular company.

I have never tested it anywhere but the midwest, so it may have problems at high altitude - not at all a problem here though.
