Define "affordable"...
You can get a reasonable price at homeshopcnc.com. In fact, I need to get the same basic size. My X axis linear rails are about 57", and add to that another 3" of 8020, that puts my ballscrew in the same neighborhood. I just have to figure out the machining for bearings, nuts, and the shaft to couple with the NEMA 34 motors.

Good luck with your project!

have you considered rotating the nut instead of the screw,no screw whip if you rotate the nut,just a thought,what size motors?and how high of a rapid you looking for?
