You say you want a visible beam but you won't get that with 405nm at 50-80mW. The 635nm will be faintly visible at that power and so will the 445nm. Your best bet for a visible beam AND 50-80mW would be a green laser. If you are want a 50-80mW violet for $100 I can do that for you but the beam is not going to be visible. All the other wavelengths will be more than $100 (except for green but that you're better off ordering from a Chinese website)
I remember having a 5mw 635nm with a slightly visible beam if I looked right down the pointer. I just want it to be slightly visible at night or in weather conditions. I don't want a 100+mw laser because of safety hazards, but I would still be interested in a 445nm around 50-70 mw.
lazerer.com green key chain? saw a couple reviews on the 100mW.
pretty impressing i guess. seemed to be a good laser and they
have a 50mw i believe. go here = Green Laser Pointer
