It is VERY sus for a few reasons. China does not and has never made pinball machines. In fact they have no idea what a pinball machine is. I have tried for many years to get something manufacturer there but I keep hitting brick walls when trying to describe what I want even supplying diagrams etc.
Second the wording looks almost the same as mine for my DMD replacement board here:
http://www.homepin.com/pcbs.htmlThirdly electronics in China ARE NOT manufactured in Xian - electronics is 99% concentrated in the Guangdong provice and more specifically around Shenzhen and Donguan. Arcade parts almost all come from the other side of the river from Guangzhou in a suburb call Panyu.
I am currently assisting a Brisbane buyer whe sent US$10K to China a week ago and the seller dissapeared overnight. We are hot on their trail but realistically have about a 25% chance at best of recovering the funds.
I think this is just another of the millions of scams running.
