The only real versions of the Sandtrooper that I know of were done by Haps and a skin done by Intone. I know of know others. The one I am doing is based off of DT's model. That particular version had not been done before to my knowledge.
Yeah I started one but didn't get too far with it. It's something I'd like to do at some point if I can ever find time. Right now, it's in the same boat as Qui-gon
