@ Colin - Thanks for the link to Fourth Axis. I was thinking of getting a small milling system, the MX-20 plus 4th Axis might be perfect for me. I just have one question about the noise when operating. How loud is this thing? Is it reasonable to operate next to your PC and still have a telephone conversation? What about when milling aluminum or brass? I am thinking to operate in my apartment or perhaps in my office...

Thanks,
jonah
