Comparison of Electronics
At the date of this edit ( May 2012 ), the IRC channel recommends RAMPS as feature-rich, Sanguinololu as "just works" and Gen7 for the do-it-yourselfer. You can always go there and ask for additional advice, of course.

- The above chart compares "complete" RepRap electronics systems -- the stepper motors plug into one side, and the USB cable from the laptop plugs into the other side. Such systems often include 4 identical stepper driver boards, one for X, Y, Z, and Extrude motors. For a chart comparing stepper driver boards, see stepper motor driver#Stepper drivers.
