Yea, I am currently talking to someone from the FaceBook page, BITMAINtech.  It looks to be the most legit one, however; the person I am messaging just requested I send them 1.057 BTC to a BTC address they just provided.

.97 for the S3
.087 for Shipping to US

Which I'm not going to go.

I requested that they create an order for me on the main Bitmain website under my profile and then I would submit a payment.
