I am offering my BFL 60 GH/s miner (SGL600G) for sale. It is marked number 000656 received it Aug 22, 2013 and as of today Aug 28 has earned me 2.5 BTC. It generates about .5 BTC every 26 hours. I ordered it on June 29 2012 and as far as I know they have shipped units ordered up to July 15, 2012.
I'm asking $6000.00 CAD bank or wire transfer, local pickup or 10% discount using BTC. I am accepting offers but am torn between selling it and keeping it. It's a great unit and I have another coming shortly. It is loud (i.e. hair dryer on low).
I have taken exceptional care with it running it in a cool place. The unit reports 60 deg C. I can take photos or video of the unit and the performance numbers on screen as verification. I will ship it immediately and send photos and tracking information. I understand that BFL offers a one year warranty even if sold to another person but I can't confirm this. There is a defect with the power supply where a volt 110/220 switch is pushed back into the unit but it still functions.
If you are interested or have questions please email me.
