A whole pound of high quality solder. Bought a soldering coil at the same time, a match made in heaven. Use it to solder lots of small electronics. Don't forget to bring solder, tin and/or flux. It's a good solder, I've enjoyed working with it so far. I was able to use it to solder 28 to 0 gauge wire. It will do what you need for 99% of most projects. Kester makes some of the best solder (even the US military uses it).
