I have two of the 3000H. I haven't run mine yet. Is yours from KY Louisville. I remember one on E-Bay from there. I hear they are good lathes. Both of mine look capable. I am not familar with Mach3. CNC isn't really hard to learn. Its more like Simon Says and connect the dots put together. I think the Dynamyte Lathes are probably the better table top lathes out there. A few others that might compare are the Rhino 8 and the South Bend Magna turn.
