I'm finding brand new S9i 14 th in the states that I can physically pick up and avoid shipping altogether. $220.00 WITH PSU in original unopened box. Then I pop the ASICBoost Frimware upgrade on them and I can't believe how reliable smooth and efficient these units are. These are my favorite of all S9's to date. I'm sub .05 per Kwh so it's an easy call. I have absolutely no reason to even think about these new units. Not to mention, they haven't been running enough to get sense of their reliability. These things could very well turn out to be an RMA fest.
