Where can I buy a good laser pointer?

Hey, guys
I want to buy a 50mw green laser pen for my coming meeting presentation and a 30mw laser pointer for the flashlight using. I am more likely to get them at online shops, as a matter of fact, my friend purchased a 200mw green laser pointer, and deep down, I was totally floored by the top quality of its 200mw green laser. Besides, he got a Blue Beam Laser Pointer for free! He told me that that one was bought form an prominent wholesale top quality and famous online high power laser pointer store. But he had no idea of the website of a good low power laser pointer. Is there someone telling me valuable information about it? I will be appreciated with your helping! (Plus: The 30mw laser pointer I want should be a red Beam Laser pen.)
