I wouldn't buy either of 'em as well, but it's perhaps not as straight forward as it seems

The Chinese 6040: Warranty & support? Good luck on that one. Mach 3? Need to buy it . Yes you can use EMC2 for free, but it's not
particularly suitable for most people just getting into CNC.
Apparently a reasonable dexterous person can operate the axes better than the control box supplied.
Most people seem to ditch it and buy or build another for 2-300 quid.
So that + Mach3 licence narrows the gap by about £400

Eagle includes Mach3, 12 months Warranty (6 on spindle) & Support
So all in all for a novice CNC user I would of thought the Warranty & support (which is apparently good) of the Eagle Makes it a lot closer
than it would first seem.
