Hi Jim
We just purchased a 4' X 8' ATC machine from Dexian (do not use them), the machine is beautiful but like a lot of the Chinese vendors their post sale support sucks. I ordered the machine in May and received it in September, Software is not OEM it is a copy that does not work, bought the machine with a Syntec Control and their is no english support. The equipment was delivered with no manuals, drawings or wiring diagrams. We are making arrangements to install a new MachMotion control that runs Mach3 and has US and english support, online training videos and tech support that we can talk to and can do online diagnostics real time.
No matter who you use in China their prices are all the same, I would spend more time investigating their post sale support because they will tell you anything to get the sale.
The machine listed below was $23570USD
PS: go with the servos, or machine runs smooth as glass.
