Our Kit-2 is $399 for 3 servo drivers and 3 motors. It will produce
a smooth 25-30 ipm on a Sherline. Most of the components are
available seperately.

Check under kits. The motors are new but surplus, similar to the
Pittmann Express GM9236S015, with encoders. There is a very limited
supply of the motors and at present usage, it will probably be
exhausted within about 2 months.
