A quick note about something I didn't mention yet. Fire. This is a laser beam firing at combustable materials after all. I've read the horror stories and got another one from the guys at FSL when I picked up my laser, so I decided early on to buy a proper fire extinguisher. I did the research and you don't want to use your standard wet chemical fire extinguisher around anything you care about, especially electronics. It's corrosive and very hard to clean up. That leaves CO2 or Halotron. Halotron is more expensive but covers a bit more as you can see in the chart below.
So I spent the $117 and got a Kidde Halotron Fire Extinguisher, 2-1/2-Pound extinguisher off Amazon. Supposedly the clean up isn't bad and it won't kill the laser if I have to use it. It now sits under the desk ready to grab.
