1395USD for that? It will not return your money, especially if you include deliver, tax and a power supply.
I assume you have solar power or wind power to run this, that is the only way to make this pay. They have priced this way too high. I was waiting for 700USD to come up but when I saw 1300USD....whaaaaaat (in the voice of mo).
Currently my S7-LN is slowly losing its fight against difficulty v's electricity. Looks like the S9 is the only one that can earn but that is a high price too.
