Hmm... See I'm actually looking for a junker so I can build a better BM Cheetor (tm) and I want the ball jointed arm really. What I might do is buy some 2 - part resin and cast the arm. Don't really care for the transparent parts because I'll be repainting him.

Thanks anyway guys you have been helpful and at least I know where to nab a BM Cheetor if I have to
