Arduino makes a great introduction to microcontrollers, and has plenty of IO to do what you need.

They can run either 2-or-4 lines each 14 digital io pins means you can run either 3 or 7 steppers depending on circuit.

Thanks Frollard, that really helps me out a lot. It also seems like the kits are really cheap - relatively speaking. There are no suppliers here in Australia who can provide kits, but I am in no hurry. Thanks again
If its 'right' please mark answered!
