I am working on getting my Rebel Fleet Trooper costume done I now have the boots which need modifing the Helmet, pistol here is a photo of the helmet the cost was real good and the quality is just great the only thing is I need to paint it grey to match the ones from the movie and one of the best parts is the visor is accualy see through unlike most I looked at which were painted on. I was thinking of making my own til I figured the cost would be way more to do that Igot mine through studio Creations heres the link for anyone who is interested. http://www.studiocreations.com

I only found one other that was better but the cost was way over my budget that was the company that accually made them for the movie but for one that is inexpencive you can't beat where I got mine. here is a photo of it.

Good luck putting the costume together & make sure you post a picture when it's finished.
