I bought this directly from Bitmain (not some BS third party scammer site) and can provide a copy of the valid purchase certificate.  I just joined Bitcointalk but I am a real person and I am from the US... I also have an active ebay account from 2009 with 100% feedback that can be validated.

not posting a for sale price... just PM me with what you are willing to spend on the unit and we can go from there.  I can do paypal but would need to be via friends and family because of all the negative paypal press on bitcoin related purchases.  I can also accept BTC as well as cash if you are local.  Again, real person... not a fake scammer.

Willing to maybe trade up or down as well but mostly looking to sell for $.

Thank you
