I myself would go with DX. That is one of my fav online stores. But, if you live in the USA, you cant order lasers with an output greater than 5mW. I got a bunch of lasers off there before FDA restricted that. For just a pointer of DX, i'd get the true 50mW green laser pointer.It is very bright, and can pop balloons. It is just at the peak where it uses just enough of the 2 AAA's power to last long enough, but not eat up power. As opposed to buying a 100mw green laser pointer, which would be pointless if it runs off two AAA's--which DX's do. There are also tactical pointers running of rechargable CR's, ranging from 20mW-200mW on DX. Those i have never tested, but i assume due to the power source, they would last a bit. If you want a laser that uses just enough power to not kill the source right away, and is insanely bright for nighttime, get either the true 30mW or true 50mW green laser pointer..price ranging from
15-25 bucks. Worth every penny of your purchase.
