You can drive the motor in any laser printer scanner head. It's only a problem
getting motors if you want to build your own head and optics.

You could pull apart an old hard-disk and mount a mirror on the platter.
Drive the 3-phase motor yourself. At 30k rpm, you'll need to be very good
at balancing/centralizing the mirror, and have it ∗firmly∗ stuck down or
it might launch off in to outer space.
