whats the most reliable lighter?

My favorite and most relable lighter is the XIKAR EX Windproof Lighter. I could light a cigar while driving in my vehicle with my window down.

My gas stove is my most reliable lighter.

Lots of folks use these too, I have had one for about a year now and it is also very dependable. Holds a bunch of fuel and good flame. Only negative is the fuel adjustment valve is not too precise but works ok. Cheap solution to outdoor cigar smoking:

Personally. I have a Blazer PB 207, a Ronson and an old ST Dupont Xtend. My favorite by far out of these is the Dupont, but maybe that's because it goes for ~$150 for the old ones (you get what you pay for?). But the Blazer is relatively inexpensive (I picked mine up for $25 on Amazon). I just received the Ronson last night from a friend, and it seems like a good (cheap) reliable lighter. I think it is a bit of personal preference. However, I would recommend you get a single flame because it is hard to correct a bad burn on a cigar with a two or three flame torch.
