A very handy tool set to have is an allen wrench set. You'll eventually need some of them later, but the kit has them in lots of various sizes. I found the size I need for my guitar in minutes. It's always good to have a set of allen wrenches, and you can find them at hardware stores, like home depot, or someplace like that. I don't know how much they cost, but they can't be very expensive. I'm going to guess (not sure) under $25.
Good Luck!
