I have the Weller P2KC Portasol Professional Self-igniting Cordless Butane Soldering Iron Kit. I really like it. It comes with a tip, cutter, and hot air tips. It's great for working in the car and the hot air tips are great for shrink tube. I tried a cordless electric one and it sucked...for light duty, I'd say go with this one, get a 'station' style one if you have a bunch of work to do...
