I've been using Ronsons for a while. I like them when they work but sometimes they just don't...so I normally bring three with me.

I've gotten kind of tired of that so I recently bought a Xikar Tech lighter off Amazon for $20 new. Great deal, $10 off MSRP and came in a sealed package. It feels like much better quality than the Ronsons and holds twice as much fluid(if not more), plus you can see the fluid level.
