Hmm, the site seems to have switched. . . Oh, well.
The green pointers at
www.ledshoppe.com are generally well regarded as far as cheapies go. Only thing is, they ship from China, so you could be in for a bit of a wait (mine took 13 days.)
The pointers they sell seem to be of a better build quality, and at least near the stated output (some people have gotten ones that are grossly over spec, meaning they output MUCH more that the stated rating.)
Customer service reviews have been positive. From what I've heard, if you get a dud, they'll replace it. They seem to waffle on whether they want the dud shipped back, though.
I got the 50mw version, and I'm generally pleased.
(Just to be clear, I'm talking about the pen-style pointers; black body, silver aperture cap, silver battery tube. 2xAAAs.)
