Soldering Iron....

I would secon what rmchrgr said. The snap on one is actually a relabeled weller but a nice one to have. I have the weller butane one and use it daily at work. I like the versatility of it. I would also suggest using a thin solder. I use a .6mm and it is great as it takes less heat to get it to flow and works well on wire as well as pc board repairs. The only thing you have to watch o. The butane is leaving it in extreme cold. Before using it you have to warm it up so it will light.
