Keychain laser?

[Phaserburn]

I am looking for a keychain laser pointer. What are the good models, and where to get them? I am a noob; what specs should I be looking for here? Generic yet specific help wanted!

Shorter wavelength is always better. A 635nm laser will look brighter than a 650nm or 670nm one of equal power.
Power output will be no higher than 5mW in red keychain laser pointers. At least those I know about. The closer you can get to 5mW, the better.

I don't have any "where to buy" information about keychain laser pointers, sorry about that.
