Stu, Depending on your machine size, these motors and reducer boxes
may be a solution for you:

They are newly manufactured to our specs. The target applications
are desktop machines like Sherline, Taig and the mini/micro mills,
small lathes, foam hot wire cutters, small CNC routers, etc. They
come equipped with 500 line encoders.

The motors are matched to the $65, DeskCNC, SV-500 servo drivers.
