I've got a couple of cheapies in the pack, backed up by matches and a sparklite.
I have one of these for EDC (mostly for curing heat shrink now that I gave up smoking), works better than I expected, lighter and less bulky than a zippo, the candle function is nice too.
Austrian Lighter I'm planning on trying out one of these, the extendable nozzle looks handy
