If you want to spend a lot of time you could probably get a ramps board to work with the UNO. You would have to wire it pin to pin as I think the RAMPS board wants an Arduino Mega 2560 or similar. Other options include the original pololu electronics design that you can do on a strip board.
If you don't use the UNO you could build a Sanguinololu or Gen7 board DIY for around $30 or so depending on your junkbox and skill. Pololu drivers will add another $40 to that. So about $70 for a complete system.
And of course you could buy a Sanguish board from me. $40 + shipping which includes the drivers.
