Hello,
I have three lightly used Bitmain S5 units for sale for 1.65 BTC each. Price includes shipping (ground) to lower 48 states (US). These have been run on and off for about a month at stock speed. There are no issues with any of them. They are in prefect shape. I am downsizing my number of small (non rack) miners as I don't really have room for them. I just bought too many when they were available!
I would also consider trade for SP30, 31, or 35 with additional funds available. I am fine with escrow through OGnasty but you pay escrow fees.
Let me know if you have any questions.
Thanks,
Ryan
