Oh, man, if ONLY! I love Roadbuster, and this mold is great for him, I just can't stand passing off a Hotshot head as everyone's favorite walking armory.
If I could get a hold of one cheaply, I would love too. It would be nice to find a figure with a suitable head that is cheaper and easier to get it, though.
After seeing this, I may just have to make a mold and cast from my g1 figs head. I like these colors better than the real one coming out. maybe it's because it's more muted and not so shiny and bright, course it could have just been the pics I saw from Botcon as well.... Either way, very cool.
