Need help in choosing a quality solder iron (Butane)

I am looking to purchase a gas-powered solder iron to do work on my mini R/C's, along with other small electronics (i.e. wiring car stereos, blinkers, heat-shrink, etc.). I'm not too familiar with what features there are, or what I would need to look for.

If anyone has some solid knowledge in this area, I would be greatful if they could share their wisdom.

Also are their any particular brands that I should consider or avoid?

Thanks in advance!
