I heard about the somewhat tender nature of these medicom bodies too, but they've managed to deal with whatever i've dished out on them pose wise.
However, they are definately -not- for playing with, unless your very brave, the price just doesn't allow it, however these RAH-1 Kai bodies do seem alot studier than i had previously heard, certainly are stiffer than the anime medicom figures i have.
It goes without saying, if your a spidey fan, the satisfaction from having these figures will far outweigh the cost of buying them, in my oppinion. Frankly, its given me more satisfaction than owning one of those movie suit replicas we see in the main thread here.
I'll definately post up pics of Red and blue when he arrives, my website should be up and running soon too, so i'll do full reviews on all three.
