I have a simple 60 watt soldering iron that I picked up from the hobby shop. I believe it's made by hobbico and works perfect for all of the soldering I do (esc, batteries, etc..) and only paid around 10 bucks or so. A soldering station would be nice but I only really need to solder when I get a new ESC or batteries. Plus, it's easy to just wrap up and throw in the tool box for when I need it next.
