    A site called Greatest Deals Ever has them if anyone is interested. I got one a few years ago but it was 80 dollars refurbished. Seems they are coming way down now. The interesting thing about these powerful green lasers is the effect they have on some minerals, like quartz. In the philly museum they have a great mineralogy display and I went nuts shining my laser in all the transparent ones, they had a quartz crystal the size of a log and it was incredible what the laser revealed about the internal structure. Great fun.
