I am a dedicated smoker (cigarettes, pipes) and I had used a zippo for many years till I found this lighter:

I fill it around once a month and use it at least 30 times a day. I have used it for soldering purposes, heating needles and -just for trying once- for boiling water in foil. It has a flame lock so you do not need to keep pushing the button for long. (or just you want to throw it on leaking gas to blow up bad guy's car <img src="images/graemlins/smile.gif" alt="" /> ) Also the flame is narrow like a real torch and you can point it at somewhere easily. It burns long and hot enough to dry wet tinder etc. I have been using it for about three years outdoors and indoors. If you can find something similar go for it.
