As everybody at the Stumptown herf can attest to, my Ronson JetLite lighter has survived abuse and get passed around all-night for lighting and touch-ups. Sucker is durable, burns almost anything, and is cheap.
Toasting a cigar with the JetLite takes a bit of trickery holding it far enough away. Don't wanna dump it right in the flame. Also holding the lighter vertical and the cigar at a 45-ish degree angle over the flame does help.
Good luck with your lighter search. Like cigars and cutters, it's all about personal preference and comfort.
