Are these still viable?
If so, which ones work well (high reliability, easy installation, non-contacting) and are reasonably priced?

For wheeled shooter speed measurement we've had good luck with this gear tooth sensor from Allegro Microsystems:

As long as you can get the face of the sensor close enough to the teeth of a ferrous metal gear, you'll see one pulse per tooth that passes. They're around $7 each.
