I want to convert my F1 so I can you Mach3 to run it...

The 3 axis kit I'm looking at is this http://www.probotix.com/3_axis_stepp...or_driver_kit/

The problem is that I want to control the spindle as well. It's a 180V / 3Amp / 440W (~0.8HP) DC brushed motor. If anyone has a suggestion for a "cheap" solution I'll be happy to hear it. Thanks!
