MiniMe,
Have you had any problems with the torch lighters at altitudes greater than 5,000 feet. I was looking into buying one and the guy that was selling it to me (the store owner, in fact) said that if he were me he wouldn't spend the money, because he didn't think I'd be happy with it where I was going. He sold me a 1.00 bic instead.
So much for my cynicism,
