How common are these things? Were they only sold at the Tokyo Game Show? I recently ran into a silver Japanese version...are they less common than the blue ones and what would you say a silver one is worth? $30 a good deal? I saw some on ebay, but the silver ones on there look quite over priced. Are there any other colors or variations of these?
By the way, I think there's a 'whats it worth' thread somewhere but haven't found it. My apologies if this is the wrong forum.
