I wish I could find an old Vu-lighter. They worked about the same as a Zippo, but had a clear base filled with lighter fluid, and a smaller "cotton" area above. When it wouldn't light anymore, you turned it upside down, pushed a little button for a few seconds, and fluid flowed into the cotton. That way, you did not have the fuel evaporation problem you have with a Zippo. Might have to check on e-bay or something I guess...
