For my money, I think it is worth sticking with the Pertronix. When I get back from the Ford show in Carlisle, I'll explain a sure-fire way to install the Pertronix that makes no modifications to the wiring in the car and still delivers a full 12 volts to the Pertronix module.
I've been using Pertronix for over 20 years on both my cars with no issues.
