I actually used Pololu's laser-cutting service to make some brass cutouts for one of my projects. The sales staff is super helpful and willing to answer questions and also to go the extra mile. I will definitely be using this service in the future.

I also use a lot of their other motor controller boards and voltage regulators. Top notch quality on par or better than Adafruit, and the form factor is incredible as well. For any hobbyist with space constraints (I build custom Lightsabers) the Pololu boards are amazing!
