I'm in the "If it ain't broke, don't fix it" camp. If your points system is working properly, leave it alone. I've put 10k+ miles on Ol' Roy with no worries. Starts at the touch of the button and runs like a Swiss watch.
All of my vehicles have breaker points and they work fabulously. I've never been stranded by a breaker point ignition. A couple hundred thousand miles with no problems.
I did have an HEI module fail on a Monte Carlo a long time ago.
If you insist on converting, go with HEI and not Pertronix.
If you styick with points, get on of Jon G's (above) 200,000 hour condensers. You won't regret sticking with points if you do.
