They now have blue, green, red, and yellow. Blue and yellow are still obnoxiously expensive. Still if you like lasers, look at www.wickedlasers.com. Mmmmm, 300mW green lasers.
I keep waiting for them to try to regulate sales of blue and green laser pointers because of the complaints of aircraft operators.
Their range is so much longer than the red ones, if you use them for pointing out constellations, you run the risk of momentarily blinding someone flying a plane.
