But, there's also my Universal Stepper Controller, for only $200.  This 
is step/dir output, encoder
input if you have encoders, opto-isolated digital input and solid state 
relay output.  See
http://pico-systems.com/univstep.html for more info.  By the way, it has 
special features
for the Gecko drive's timing requirements on the direction signal.
