Looks a decent little machine

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.

the eagle will certainly have better drives (probably moons' SR24 drives) vs. some nasty yoocnc all in one stepper driver board in the Ebay Chinese one (not to mentioned a couple of hundred quid's worth of VFD/spindle....vs the £50 air cooled spindle that comes with the Ebay chinese machine)

In my opinion, the Eagle should be a touch cheaper (on a 'totalling up what it's got over the Ebay Chinese machine' basis) ...but that's probably because the seller has had to build in some fat to give Ebay their slice of the selling action - if I was wanting this particular style of 6040 machine, I'd be inclined to go direct to the seller of the Eagle & see if you can strike a lower priced deal (on account there'd be no Ebay fees), see if you can collect with cash (no paypal fees etc)
