some months ago i also looked for an chinese cnc machine, but thank god i bought a used german machine from uk (high z).
during this time i bought a chinese motorcyle(skyteam) and latest a chinese Handy(vkworld) and this companys are really big,
but the dont offer customer Service. from skyteam i only needed the spare parts catalogue and from vkworld a Manual to update the phone!
i tried it twenty times and got no answer! so much to the good customer Service chinese companys offer, the Quality of the products isnt any better
most time ;-(. i would say buying a chinese product is most time like playing russian roulette!
