Sorry about your situation Snake. You'll be on your feet in no time.
As for sounds in the sabres, I have seen some sites recently that has instructions for adding them(in some creative ways). I have also found sites that have the 'blades' and are supposedly durable. Those get fairly expensive though, around $75+. Wish I remembered the sites. Do searches for "how to build a lightsabre", build a lightsabre", homemade lightsabre", etc... You might get lucky.
I am actually going to give it a shot and try my hand at building one(no blade or sound for now). Going to put a part list together tonight and buy the stuff tomorrow.
