There was a guy a while ago from Phoenix who bought one and loved it. Then, he stopped posting. Dongfang seem to be a decent brand, and Venom Motorsports sells a few of their models including, I believe the Ghost (be aware, they rename bikes to alphanumeric names like 'Venom X22' etc) but they are Dongfang models). The reason I mention Venom is they have a good reputation, and stand by their products, so wouldn't sell defective bikes that they have to deal with warranty issues. So, buy it through them would be my advice.
E dit: they don't name it alphanumerically, but do call it the Venom Ghost.
