Spent the day in Toyama, even got out to the Toys R Us near the University. While I was there, I found these: Gundam Army Men. I bought three bags of each faction. Very very cool. They look to be a good match for 1/300th or so.
We'll have to see how they take paint. I hear Army Painter paints stick to softer plastic pretty damn well. Naturally I'm currently stocked with Vallejo.
