Well I haven't tried this myself, but I can't see why Contact
Breakers (Points) from a car ignition system wouldn't work if
carefully setup. They're cheap, readily available, come in many
configurations and can be safely overun by 1 or 2 mm. They are also
designed to activate instantly (for consistant ignition timing) and
so should have good repeat.

Hope this helps, Martin.
