I was noticing that nobody seems interested in THK's and NSK's rolled ballscrews. Is there any reason for this? They don't seem much more expensive than mcmaster, reid tool, nook, or any of those other brands. And I think anyone in their right mind would choose THK over Nooks semi-precision line. I was just looking at one of THK's screws. 14mm rolled screws with a C7 accuracy (.05mm per 300 mm, freaking awesome). A 1500 mm screw with two nuts would be ~$350. I could not find a backlash rating but, I bet its less than 1 mm.
