As a tech that has experienced various machines from multiple countries...my experience with Chinese machine have been challenging with the lack of documentation, 12 hour time differences to speak to the factory, ill fitting parts, missing connection and software that is very difficult to use as there is no manual to look at for operation/training.

I would speed the extra money for being able to have support in my time zone, a manual/cd for the operation and technical aspect of my machine.

A great price means nothing if you spend weeks, if not months trying to get the equipment up and running.
