I love both the Vector and Xikar lighters that I've gotten. Vector Heatran is my triple torch "go-to." it has a big tank and a built-in cigar punch on the bottom. I have some single torch Xikars that are awesome, too!

For awesome, bargain single torch lighters, try the Ronson Jetlite - available at Wal-mart or some drug stores. They're less than $5 usually and work great (and if you lose it, you can just buy another without crying too much).
