Hey,
Has anyone tried using http://www.sparkfun.com/products/10507 as a stepper driver for a reprap?
It seems to fit all the specifications: 2 amps, bipolar, 1/16th microstepping, plus the price is pretty good too.

That's actually more expensive than 4 Pololu 1201s. If that one board breaks, you probably will need to replace the whole board. But with the Pololu, you only have to replace the one that broke.

Exactly. The SparkFun board isn't really economical, plus you have an extra board that has to be wired to. With RAMPS or Sanguinololu, the stepper drivers plug right in with no extra wiring.
