We use these encoders.

Initially, we used the direction portion of it with the Encoder card. The problem with this is that the encoder needs to calibrated VERY WELL. 2 of our wheels we couldnt get the signals at 90 degrees or even 80 degrees because there was not enough play on the mount. We decided just to wire one of the encoders on each wheel directly to the computer and not use the encoder cards. Our program figures out the direction.
Ironically, this procedure wound up frying our encoders (not through fault of the encoders themselves)... A 12V signal was *accidentally* applied to the 5V Digital I/O bus by a *non-electrical* member of the team. This fried the encoders. What's ironic about this, is that had we been using the encoder cards, this would not have broken the encoders.

Anyway, thats my opinion.
