When I were a lad... Back when I worked for Real World Interface we built our
own shaft encoders by drilling holes in a gear blank ( any number you like )
and ran it through a opto-isolator ( led-reciever pair ).  This requires
a little mounting hardware but you ought to able to squeak under the $10 mark.

But you tell kids that these days and they won't believe ya! ;-)
