not familiar with Haase, but I picked up a BZT750 a couple of years ago. i did not use their motors (I put on 60mm Berger Lahr/Telemecanique's). It a good machine and I bought it because I liked the mechanical transmission of the x axis. I only have ~350 hours on it, but it holds very repeatable tolerances. Aside from lubrication, it only trouble was it required some tightening to one of the bearing preloads (a screw that had come loose a little).
