That might be just the ticket George. Does it use IR or RF?  RF would be better for me because I need to control from within a room.  I have been thinking along the same lines with this thiscontroller  to drive DC gear motors.  Your find has built in stepper drivers though.  And for $6!  I couldn't resist.  I ordered a couple.

In the mean time, my R32 and CNC V3 arrived.  So I am going to play with them for a bit.
