Ya I just scored another. Somebody had like 40 of them @ no reserve. Paid less than what bitmain sells them for so dude took a hit! At the time that batch shipped they were TTM!
Be real careful when buying off of ebay. There are a ton of scams out there - especially when they have multiple listings. I almost pulled the trigger on 40 of them but the guy cooled off his communication when I asked for his contact information and proof of ownership / purchase from bitmain. About 6 hours later I got an email from ebay saying that someone had hacked the seller's account.
Mine were also bought off of ebay, so there are reputable ones out there too.
