The sculptor of this kit was the famous Takeya. Many masterpiece kits was sculpted by him, including Aliens, Predators, Japanese gods/monsters, etc. This kit is one of the coolest one I've seen. Look at all those Aliens!
If you can't find this awesome kit, you can try Sideshow Collectibles for a prepainted statues. (Or you can buy other works of him, there's plenty of them in Japan recently)
