Was wondering, is anyone else in to this? I saw them last year in Japan, and was going to grab a few, but never got around to picking them up. I'm not into collecting miniatures, thoguh I did think these were pretty neat. Tomy now makes these for the Bus Collection as well.
Link's in Japanese. You can translate with Google or Babelfish, thoguh I have Rikaichan installed on Firefox so it works automatically for me.
