Other than the HiSaturn Navi, I personally prefer the US black model (1 with oval buttons). I prefer black over white + the model 1 just looks more sleek with the access light and the glossy instrument(?) panel strip.
Joe, I do have an extra MPEG card - the JVC twin operator. I was thinking about selling it in a package with a few compatible games - Lunar SS MPEG, JP Gungriffon, and maybe Sakura Taisen Steam Radio Show (I say maybe cause I have 2 copies of the first 2 games, but not ST:SRS). I'm not quite sure what the fair value would be, but PM me if you're interested.
