does anyone know of any cheap class II (<1mW) green lasers? a friend wants a laser to play with her cats, and if a cat's eye is anything like a human eye i'd guess green would be brighter to them too... and with <1mW she'd probably not have to be too worried about damaging the cat's eyes accidentally, but all the green class IIs i can find (including one site - blue sky marketing - unscrupulously saying a 1mW green at night is like a lightsaber, and having an image of what's obviously either a much more powerful laser or a photography trick) are a lot more expensive than the cheap 5mWs that are around (cores, destructive gear, etc)... so, any class IIs that are £20 ($40) or under?
