+1 on the chisel tip recommendation. Also, I would opt for a pencil style iron rather than a gun. The pencil allows for greater maneuverability in tight quarters. I know that cost is a factor, but you owe it to yourself to get an iron that has variable temperature control (and not just a high/low wattage selector). If you go with a cheap Radio Shack model and end up doing much soldering at all, you will likely end up buying a decent soldering station anyway. Save the aggravation and go with the better tool to begin with. I'm happy with the Weller WES51 as a decent compromise between cost and features.
