I've had good luck with the Pertronix Ignitors on Studebakers. Others have had issues with them quitting with no warning, so they carry a set of points and condenser in the glove box. The one thing you must be super careful about though, at least on the earlier versions (Ignitor I ?) is that you cannot leave the ignition in the 'run' position for long periods of time without the engine running or it will damage/zap the electronics.
I've heard lots of folks that say the Pertronix made the car start so much easier, and run so much better. I didn't see much difference, but the cars I installed them on had the ignition system in very good shape (wires, caps, plugs, points, etc).
