Does anybody out there know of a good source for optical encoders or
digital potentiometers?  I need one that fits the following specs:

1.  small size - about 1.5 x 2.5 inches, preferably a little smaller
2.  360 to 512 CPR (counts per revolution)
3.  TTL/CMOS outputs
4.  low cost -- about a $100 or less in quantity
5.  lab use only -- no use for hermetically sealed case or wide temp range

I would especially like the unit to include a small shaft with bearings
to reduce friction.

Please respond directly -- I will be happy to post a summary in a week for
other interested people.

Thanks in advance.  I appreciate your cooperation!!!
