Only thing I'm not sure about is how much we paid for them!
We also used these Grayhill encoders on our FIRST robot last year and they worked great for us. We use them on almost all of our robots on our college level team as well, except for a few times when we've bought motors with built-in encoders.

The output shaft of the grayhill is the perfect size for press fitting a K'NEX gear onto as well, which we have used successfully as the interface with an actual shaft in your drivetrain.
