If this is something that you plan to use everyday, invest a little money into it and make your life that much easier. Good tools are a god send on your arms, mind and knowing your are doing things properly.
If this is a one off project and it will eind up in a drawer never to be used again, get the cheapest thing at walmart, kmart or harbor freight.
Tools that I use are one thing I am picky about. Soldering Iron, Volt meter and a screwdriver set.
