I have worked with Haas machines off and on for about 14 years. Basically they do what the specs say they will do (not what a salesman says necessarily).
If you have cash, and really shop around hard, you can find good used machines for some very decent prices. By good, I mean solid. You might have to spend some bucks getting some repairs done or even a minor rebuild. But for the right price, I think it is worth it.
