Check these out, Monkey School has a led levistick which opperates on a single AAA battery around the $40 range. Here is a link to check them out. I got to play with one not to long ago and there awesome. It got me glow-wanding for cheap. I dont think there website is up yet but I got mine directly from the guys making them, at a show.
I was so excited to see this, cant wait for the website to be up
