What application do you mean? If you mean speed encoders, the banebot encoders that fit on the transmissions is a very easy solution (http://banebots.com/pc/ELECTRONICS/EN-G0561-KT).
If you mean a position sensor, USDigital has a great absolute encoder that we used to link our left and right side drives together so we didn't have a chain across the robot. (http://www.usdigital.com/products/en...ary/shaft/ma3/)
USDigital also has rotary encoders that you can use with a wheel for floor speed if you are looking to do some traction control.
Ok USDigital IS pricey but I can't argue with how easy they were to use (a simple analog signal) and reliability. I think they are worth a look.
