Which CNC 3020 machine on ebay is genuine?

Hi guys,
Pretty impressed by this forum.
I am planning to buy a PCB Miller for home use primarily.
After going through many threads on this forum , I have concluded that CNC3020 is the right choice, as I am interested in making prototypes only.
But the problem is, there are so many sellers on eBay - some genuine & others fake.
Kindly advise if anyone can help distinguish them or please provide inputs from your personal experience with any specific seller.
Also, is there any other place other than eBay, like the original manufacturer's website, for buying?

Any help appreciated.

I didn't find the right solution from the Internet.
