I can finaly say that I have my own MR saber. it was made with the MR saber kit at radioshack: linky
Well, I picked one up today and settled on a design:
It has a luxeon setup: single LED in the blade.
It is amazing in low light conditions:
i can also make it green or red. Just a couple of twists, slide a section down, flip a switch, and put the parts back.
Pretty nice for $70
the emitters (3: Luke/Obi-Wan-style, Vader-style, and Anakin/Luke-style) are metal, as are the three pommels. the rest of the hilt parts are plastic.
If anyone wants, I'll snap pics of the multiple parts for everyone to check out.
Just thought I'd share my new weapon for my RL application in March
