$6500 is not expensive. Cointerra is offering their JUNE BATCH at 6k. Cognitive Capital is offering you a 3 month head start with the same unit, which happens to be the most efficient on the market.
Even when using the lower hash rate (1700 Gh/s) purchasing these rigs will yield the buyer more than 400$ a week. But you'll have the edge on the market for over two months, hence the very slight premium. Pay 6k to start printing money in June when its harder and worth less or pay 6500 to start now when you get an advantage.
