Although I'm pretty sure we had another thread for where to look for TF's in Japan. I found a good place today near the Gundam store in Osaka Denden town. The store is across the road diagonaly opposite the Gundam store. On the second floor there is a whole TF aisle. They have TF's from G1, G2 ,Beast Wars, ROTF, Japanese exclusives, American Exclusives, Botcon, Fans Project, Marvel Comics, old TF paraphernalia, second hand TF's even the newest releases like Powercore combiners a bit of everything. Quite pricey though.
Ah ok, I hear its the same with the Revolchip stuff you have to get it posted, they say allow a month for delivery so it's a bit of a risk alas, I'd probably leave before it arrives. The only place I've seen those Revoltech types are at the Kaiyodo store. Not sure I will get any though, my favourite Revoltechs are the humanoid ones, be lucky not to go broke on regular Revoltechs and other toys, I've sourced 3 that I wanted so far for less than 2000 yen.
