Looking further on the AT site, they aren't at all anxious to sell motors. I did find an 1805 oz/in 2 motor 'kit', 2 motors, two of their drivers, a breakout board and a wall wart for it, presumably for a mach lathe setup. 6 Amp drivers so I assume the driver and motor are matched but I can do 6 amps with this psu. But I'm not paying $700 + shipping for the whole thing when all I need is the motor, and maybe the 20x5 Z screw & its supporting hardware they also have in a G0704/BF20 conversion kit. And at 16:15 local EDT time, the phone number in Hoffman Estates, IL, on CDT so its 3:15 their time, is being answered by a voice mail system. Does anyone have a better phone number than that one on their web page? I know you all seem to think AT is the best, but when you cannot find what you want, AND they aren't answering the phone during what should be business hours, I am not being favorably impressed. Frustrated is more like it. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
