well I have not seen a surefire flashlight but basically if you want a green laser(supremely awesome compared to a red one- green lasers the entire beam can brightly be seen for miles) you have 2 options, a pen type pointer - like the one spinning in my avatar. Or a flashlight type laser pointer (pgl-3) Depending on how much power and size you want the pen type pointers start out at 70 bucks for a 5mw unit from vitalspirit- and can be as expensive as 450 bucks for a 90mw wicked exreme (I have one on the way!!!cant wait) Or for the portable flashlight type models called a pgl from cni they are 700 bucks for a unit that generally puts out 150mw. They sell less powerful pgl units but for the money of one of them you could get a handful of penstyle pointers that put out the same power. Hope this helps.
p.s. I started here interested in led flashlights then I bought a green leadlight laser pointer and modified it and -WOW!!!- You will love a green laser I dont mess with flashlights anymore /ubbthreads/images/graemlins/thumbsup.gif
