You really wont get a green laser for under $40 dollars in the US. If you want a <5mW greenie, try the Lyra-C from LaserGlow. They are 59 dollars without shipping. They are not in the US, rather, in Canada, which is close enough, they also have fast shipping. Good Luck! If you want a higher powered laser, you'll have to fork out for an X from NOVAlasers.
so im thinking about ordering from dealextreme, how long does it usually take to ship to the US. Also i am thinking about getting one from ebay, anybody any order a laser from ebay?
