Inexpensive Laser for a simple scanner

I am building a music-responsive scanner that uses a mirror spinning on its axis and then a mirror on a servo to scan the beam.

I am looking for the most inexpensive option that fits these constraints:

Any Color
Fairly visible beam when scanned
Not a pointer format (ie NO momentary switch, and not battery powered, leads for a power supply

Any suggestions? Thanks!

I don't know a whole lot about the power required for visibility without fog, but fog would probably be reasonable.

What sort of powers are required to see a beam without fog?
Also I'm assuming once you get up to these powers they start to become a vision hazard?

Typically yes, visible beams without fog require powers greater than 5mW, which are eye hazards. With fog even 2mW red (hardest to see) is visible.

Probably somewhere in the 5-30mW range would be good for my purposes. I just can't seem to find many that aren't a pointer type.
