Lots of great suggestions to get you started. I'm glad someone finally mentioned the Dremel. Don't forget a power drill of some sort. You CAN survive with a hand held drill but they're not very accurate and mounting engines precisely is a must. Keep your eyes open for a small drill press. Micromark sells one for about $100.

Yes, the $$$ add up a little at the beginning but quality tools will outlast you.

Enjoy and welcome to the world of building.
