Are you going to be soldering on a regular basis or a once in a while event?
If you are going to be using it regularly, I recommend the Weller WD102. It's the one I purchased after much research. As a 95W soldering iron, you will not lose tip temperature when soldering larger wires keeping the time you are applying heat to the objects you are soldering to a minimum. It also has a digital readout telling you the soldering iron temperature (you specify the temperature you want and it holds it there). There are 3 programmable temperature buttons too. I have one set for circuit boards, one for 12 gauge wires, and one for servo leads.
If you are only going to be using it on occasion, then just about any 60+ watt soldering iron will work.
