I guess I am looking for more expert insight. The THK slides are so expensive, and from what I hear, so good. I haven't heard much (or looked much) about rail slides. I found some on ebay ( http://cgi.ebay.com/4-Shafts-20mmx60...QQcmdZViewItem ). I seem to be able to find more of these available then linear slides. Can anyone pro con me, or even let me know where a good source for either is?
Thanks
