You may want to have a look at US Digital website, to find appropriate encoders.
I would also suggest you to use PIC18FXX31 family. They have built-in quadrature encoder interface module with distance, direction and speed. Much easier to deal with and with extra features like noise protection too. I'm personally using PIC18F4331 and it work great with stepper + quad. encoder.
Hope this can help!

Huh? Last question was 8 months ago ? (Ooooooops)
