Does anyone out there know of an INEXPENSIVE sensor for determining
the position of a shaft?

A standard shaft encoder would be nice but they run about $85 which is a
bit steep for this home project.

I'd also like to avoid potentiometer / AtoD systems because there such
a pain to build.

Any ideas?

Thanks,
John
