rej, you have the perfect right to buy or recommend anything you want, or to trust one member over the other as you see fit, as do I.
Startup asian companies are not known for their quality control, attention to build quality, stocking spare parts or after sales support, North American companies are. I was not about to roll the dice on a purchase like this, never considered it - Does that mean I expect everyone else to follow in my footsteps ? Of course not, I really don't care what others decide to do for themselves but if someone asks, I will tell them the factors involved in my decision, and support and build quality were primary considerations [and yes, though not absolutely necessary, it does help if your support rep can speak understandable English].
CNC can be frustrating enough at times with any outfit, and any machine is prone to wear and malfunctions. Do I want to correspond with someone in China by email or post another "please help me !" thread on cnczone, or do I want stateside based support with guys that will talk to you for hours if necessary on the phone and have well established http forums where you can instantly pick the brains of dozens of experienced, helpful guys ?
Thats a no brainer to me and, once again, if you know of an asian manufacturer which offers similar after sales support, don't keep it to yourself.
Aside from support, as for actual quality, no I do not have 1st hand experience with a china made CNC machine. It is not exactly a hidden secret that the reasons in general they build things so much cheaper is that they make extensive use of:
* slave labor
* inferior materials
* poor/non existent quality control
* pirated/copied components
Go get yourself a $15 right angle grinder from harbor freight, I'll get a $125 Makita from Lowes, we'll see who is the last man standing - You won't get 1 hour on a real job, I'll be going strong for years, and yes I do have 1st hand experience in this regards, I have years ago sworn off the use of any cheap made in china junk tools, I wouldn't take one if you gave it to me and I am not inclined to give them the benefit of the doubt that they are much more meticulous with CNC machines.
