I have two lighters, a Zippo for outdoors (butane lighters blow out very easily and they don't like the cold) and a Xikar Pipeline for indoors. If you only want one lighter, then go for a Zippo. About as cheap, simple and reliable as they come.
A note on the Pipeline: unlike other butane lighters I've used this one fires every time, but it has an annoying, out-of-the-box assembly flaw. The post that holds the flint assembly to the lighter body loosens up after a week or so of use. The only way to fix it is to disassemble the lighter and tighten the screw from the inside. My new lighter loosened up within a week, so I sent it to Xikar for repair. I got a new one that did the same thing after about a week. I love the lighter otherwise, so I decided to take it apart myself and put a dab of Guntite (Loctite formulated for gunsmiths) on the screw. Problem solved. I call it an assembly flaw because they apparently don't use any thread locking compound at the factory. Considering that I had two different lighters loosen up on me right away, they must see this all the time, but somehow they don't seem to get the hint.
