I bought one of Roy's DIYCNC boards earlier this year - the System 3+
I bought it as a package with the cheapest nema23 motors.

The kit was easy to solder, and except for me not completely soldering in one of the resistor networks, worked first time. It was a doddle to set up and hasn't put a foot wrong.
I'm running all three axes at 1.5A, 1/8 step.
