Saw this and started wondering if there was anything interesting I could do with it. How much do you think it would be worth? I hate it when they don't post prices. http://denver.craigslist.org/bar/602892977.html
It appears to say 'CO2 laser' which would mean it's a high power infrared laser, very dangerous because you cannot see the light as it's blinding you. It could be used for cutting and burning though (goggles a must, and probably water cooling, too).
