Here's what I used. If you find them nice, I can give you infos. They're resin made, produced by the french Fenryll, they're called "The pygmies" and they got an honest price. They need some conversion, but you got all the needed pieces to do it in the box.
I know they're different from the original ones, but they're the most similar thing I found to represent them. The original ones are quite impossible to find.
