Lightsaber in your right hand, Ghetto-blaster on your left shoulder.
I tried to put sound from my old Luke ROTJ hasbro onto my EL, but it's too big, and I blew out the whole soundcard (they don't work on 12v). But that was made in 1995 ish, maybe it's smaller now.

Xaccers might like this, it even allows you to use a thicker walled polycarbonate blade. I got the stuff for my El saber here. FX sabers use a thinner wall poly C blade, they say you can duel with it, but you really can't. You will need at least 1/8 inch wall.
If you get to be a stickler, then I will be one too, it's not a Vulcan cannon. It's a GAU-8/A "Avenger" 30mm gattling cannon, also known as the "Burp Gun". Google it, almost every result says that.
I too would like an AGL Arms .45 Long Colt as well as a Mateba.
I'd like to see the gun that SilentScope photoshopped in the 'Unholy Fusions' thread, which I was watching Ghost In The Shell: Stand Alone Complex, and saw the very same gun.
It might have been episode 17: Angels Share, I can't find a picture though. It's in there somewhere.
