The price seems to be reasonable too, till you check the weight. At about 300 lbs including the stand, and a table that sized, I'm afraid it will have rigidity problems when carving metal. I have enough of those with my expanded table micromill now. Just a little chatter & a solid carbide mill is history, shattered edges.
How about the ZX45? At about 2 grand & 600+ lbs, no stand, what are its weak points? How hard is fitting a decently accurate Z drive to that one? -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
