Hard to beat the price of the Ningbo Ready-to-run HEI distributor, just $45 for a small-block. Add a $20 e-core coil. See Skip White Performance and others on ebay. I haven't read of problems with Pertronix Ignitor II. I definitely wouldn't use the original Ignitor since an old design which requires a ballast resistor. Ignitor III adds multi-spark and rev limiter.
I question Rusty's claim that you can get replacement parts for the old Mopar electronic ignition at any auto parts today. People have trouble finding an ECU that lasts. Many are Chinese knock-offs w/ fake TO-3 transistor.
