Choosing a motor controller

Hi all,

I've just started playing with my arduino (interfacing with a sonar, IRD2, accelerometer,...). Now I'm moving to motors.
I've seen several motor controllers on the web. I wanted to have your feedback on those ones:

  • adafruit motor shield
  • arduino motor shield v3 (easy to find in France, where I live)
  • pololu low-votlage dual serial motor ctrl

If you have other controllers in mind, please let me know
Thanks

I've used the Adafruit shield with no issues, but I like this one better:
