I got a neo-geo cart and a 1 slot MVS from him and they were packed well, and came in great working order - very clean too.
However he seems to have trouble replying to emails.
It took nearly 4 weeks to get a game from him. I had to send him a money order, sent it next day air. Expecting the same courtesy of quick shipment, I just waited. 2 weeks and no stuff. Emailed him twice, no response. Finally on the third week got an email (IN ALL CAPS LOCK w/a single run on sentence) that my board will ship by the end of the week.
So I guess just be patient and wait for your CAPS LOCK RUN ON SENTENCE ASSURING YOU EVERYTHING IS OK....
