Adafruit Product Code: 180
This 'pen-style' soldering iron is just about the best entry-level tool I've seen. It's not as powerful as a Weller WES51 but it is self-contained and easy to use. With proper care it will last for many years. Turn it off when not in use, clean the plated tip with a sponge (no filing or sanding!) The screwdriver tip is perfect for through-hole soldering and can also do some larger surface mount.
Plug is 110 US-style and can only be used in 110V countries. Comes with a very simple flip-up stand which is only marginally useful. Unless you are very careful, a 'real' soldering stand is suggested.
