Anyone run a Pertronix Ignitor III ignition module

Had one petronix II in the car for 4 years , never a problem , switched to mopar just in case things go wrong , and the shop I go to suggested it . So far 2 years no problem , oh one problem , ballast resistor went bad last year . 2 minute fix .
So Petronix good reliable , but parts if you break down could be hard to find , mopar good reliable , parts available every where
