Small sun ZY-350, 532 DPSS
Advertised, of course, 5mw on Ebay. The beamshot pictures got me, along with a $22 price tag. I still have it, and works great! Used it this past weekend, as a matter of fact.
I later got curious about the actual power out, and found this website. Oh... the memories!
EDIT: I am incorrect!!!!! I found a red laser pen when I was in the military. It had two buttons. One for steady on, one to strobe at half-second intervals. I wish I knew where that thing went... Radio Shack brand, if I remember correctly.
