it's simple, either buy securely on bitmain.com , but you will get it at your doorstep first week of October , price 40 LTC
Or pay over 6000$us for one from the July -August batch
Or pay 10k$+ for a used May batch , and you get it in 10 days up running.
I'd tell you those prices are crazy, but i've mined 12 LTC blocks and over 2 dozen Doge blocks in the past 2 months with two units.
Waiting for those numbers to fall off the cliff. Just hasn't budged too much. Maybe 50% difficulty increase from when I plugged in.
