A seller with only 11 feedback responses, and none in the past year. While there may be nothing wrong with him, there certainly is no degree of confidence. Especially in trying to sell two together in one lot, while splitting up the other. Just seems a bit strange. More importantly, as kaiserreich mentions, he's pictured the very same keyboard (same serial number) in two different auctions. Maybe he just screwed up with posting the wrong picture, but he may also be trying to scam people, and might never send the keyboards. Whenever there's something fishy like this with the listing, I'm super cautious. When the seller doesn't have any significant feedback, I will generally not bid at all. I'm not saying this seller is necessarily being purposely dishonest, but I'd be very surprised if these sell for anywhere near what the other SSKs have been selling for.
