I'm looking for a relatively inexpensive solution to control/drive four stepper motors via USB or RS232 serial -- something I can connect to a PC, which will be doing the actual control. Everything I've found through google and part-searching online is in the $200+ per axis range, and I really can't afford to pay that kind of cash right now. Does anyone know of any cheaper solutions? I don't know the details of the motors I'll be driving yet, unfortunately, but in theory things should be relatively well balanced so they should be fairly low torque/amperage.
Also, how do closed-loop servos compare to stepper motors on power and accuracy? I understand that controller hardware can be found cheaper, but I don't know where to get a solid comparison of the differences between the two technologies.
