My father (a university professor) has asked me to find him a 5mw green laser pointer, primarily for lecture-hall use. He specified that it be in the $20 (US) range, but I realize that may not be realistic. That said, let's keep it below $50.
I'm not looking for incredible brightness, match-lighting capabilities, or the ability to take down a missile in-flight. I'm more interested in knowing that it's reliable - and won't wear out quickly. It would be nice if it was physically durable, but I'm not sure that's an option.
If anyone could provide a link or two, I'd be grateful. Thanks!
