I looked into buying CO2 laser and built one own my own. It doesn't need much, just couple of aluminium extrusions for frame and V wheel for motion and couple of Nema17 motors. Also cooling for tube and optics. But laser tube life is crap, I am still waiting for cheap laser systems to come to market but it seems there is nothing cheaper than CO2 available in 60-100w range.
