I plan to get one much later, around 60-80W and use it for burning and cnc-cutting acrylic. Just want to know a few things.
1. Can the laser out of the box burn? Just give it power, cooling, and expect it to smoke stuff like crazy at 1-2ft away?
2. Is it easy to make your own power supply? Or is it best to get one that's rated the same power online.
3. For cooling, Is temperature important? Too cold == bad? I was thinking a simple radiator/fan or radiator+Peltier unit, to cool the water. If I have to, I'll use a thermo resistor and have it kill the cooling when it drops below ##F
Has anyone ever bought these cheapys from ebay?

This seller use to have 60 and 80W that I was going to get in the past, for about $200 + shipping.
then, for this example, would a PSU like this be the way to go?

Or is there better cheaper choices? I've never done CO2 lasers, so I have no idea whats good, bad, cheap, expensive. All I know is the beam is invisible, requires classes obviously, and can burn stuff, and is a pain to focus it to burn for cutting.
