Is the 3rd party vendor Amazing Armory still around? I heard that he was a scammer, but he made some good stuff and quite a few people have some of the great visors and guns he made.
I realize that it's a late answer, but ToyWiz and BrickArsenal.com just started carrying this line, and Amazing Armory is active on Flickr. Also, Firestar in the UK carries it. I hope that helps.

Also, I work for ToyWiz.com and Brickarsenal :)
