Just received my 100mw laserwave 532nm and scanpro20 from David. I'm hopefully sourcing a plate of aluminum from Laser Ben, but I couldn't wait to see it in action so I mocked up the setup on a small piece of 3/4" mdf. I'm definitely hooked!
Here's a video of it I posted on facebook: http://www.facebook.com/video/video.php?v=640264003673
Excuse the poor audio quality, my camera isn't the greatest at times. Who wants to send me a 473nm now?
