Glad to be of service.
On another note, I am in contact with the creator of these mods, and he tells me he is going to be offering the 'Co2-blast-in-tha-face' mod to the public very soon. When I asked on cost, he estimated between $250-500. A wide scope there I know, but I need it in my life so I will let you guys know how he gets on.
Oh, the Darth Vader head mod looks like an electric car aerial of some sort? I can't imagine it being too hard to hook up.
