Master Replica's has put up a demonstration video of their new replica Halo Plasma Sword on Youtube. They seem pretty damn cool, but come with a hefty price tag of $200.00 bucks. Also, you will notice that it doesn't have the pointy edges like the actual Plasma Sword does. Jasman Toys was going to release a Plasma Sword for its Halo Laser Tag set, but due to the sharp edges and other things; stopped production on them.
I do think its pretty cool, but how many of you would pick it up for $200.00? I may have to pass.
