Analog Encoder Module

I need to accurately control a small DC motor using an encoder feedback system. I am currently using a 2 inch encoder disc with an encoder module. Is there an analog (sine/cosine) encoder module similar in operation to the HP HEDS series encoder modules ? Since cost is a major concern as well, can anyone an alternative solution ? Thanks for your advice.

Last time I talked to my old group at HP (now
Agilent), they told me that their encoders were
available with sine/cosine outputs instead of digital quadrature, and that this is what the HP
inkjet printers were now using. I'll bet if you
contact their marketing group, they can tell
you what's available.
