This may be a scam. I ordered two of these at $899 on Monday through Aliexpress. I made contact with the sales guy and he seemed pretty good - was very responsive to my messages and even made contact with him on Skype. When I started inquiring yesterday morning about when they would be shipped - he went silent and this morning I woke up to an email that my order had been cancelled. I will get my money back through Visa ($899 x 2) but I find it odd they cancelled the order...that is unless they were contacted by someone who was willing to pay more for the units - who really knows. All I can say is to be careful and do not send funds via BTC or other currency.
