Observation re: the "peanut lighter" Pete mentions.
My only complaint about the good old Zippo liquid fuel lighter is that IMHO little can be done to prevent rather rapid evaporation of fuel in storage. I bought 5 peanut lighters from Countrycom, filled them, closed them tightly, and periodically tested them.
I'm confident that much, even MOST, of the fuel remained after 5 months. In fact I'm confident enough that I replaced the sparklight with the peanut in all my PSP kits. Even w/o fuel the spark will start a tinderquick or cotton-vaseline ball. I'm sold. And for $5.00.
