His one positive comment seems to be from another empeg that he sold. He has only had his eBay account since the day the empeg store closed, so my guess would be that he bought several after the price drop, before they sold out, and set up this eBay account just to sell them off.

As for his feedback rating, perhaps some of his customers weren't happy at having missed their chance from SONIC|blue and having to buy from him instead, and so they didn't leave any feedback. In my experience many users do not bother with feedback.
