Buying first green laser, deciding between these

Hi, I'm new here and i m buying my first green laser pointer. I decided on getting a cheap 5mw pointer for pointing around and other one for burning. I read around the forum and hear that O-like and Rayfoss are good choices. I don't want to spend more than around $150 for the both of them.

How are the ones i m decided on...

And since I live in the U.S. that means I HAVE TO buy a class IIIb laser with a keylock right?

lol the key lock thing makes no difference if its over 5mw its not supposed to get in but with these companies you shouldnt have to worry about it theyre pretty good at disguising them. but use the slowest shipping option. they search the rush shipments more thoroghly for some reason. i really like Ledshop just get theyre 50mw one its great for pointing around and can do minor burning tricks like popping a balloon and burning black plastic plus its only 24.99...

oh and if the second one is just for burning get a red one theyre alot cheaper
any of these will burn great
