It arrived today from China. Paid $180US for it on eBay including shipping. More info on this laser and my project here: http://laserpointerforums.com/f57/my-...

It is being run by a NST directly in the video, no rectification, thus why you can hear 50Hz pulses from the beam. It also had no flowing water (Just filled the tube), so I couldn't run it for long.
