Figurine Resin

Why isn't resin casting of figurines more popular?
it's not all that costly or time consuming as compared to ceramics (especially since you don't need a kiln), it's less messy and far more durable than plaster, and it seems like once you got it the hang of it, resin casting would be a pretty awesome hobby. am i missing something here?
if you do resin casting, what books, sites, and/or supply companies do you recommend?
thanks.
I don't resin cast, but I enjoy building resin figures. Makes a nice challenge from the plastic kits I usually build.
Maybe it's a cultural thing too, since most of the garage kits seem to come out of Asia.
