Love 'em.
I have used the Pertronix and the other non Empi one...
DO NOT USE EMPI, lots of bad reviews.

I have one in my bus. It is the petronix that I got from BugStuff at a show. I thought it was pricy, but it is par for the course. You need to be careful not to leave the key on and burn it out. And you should take the points and condenser and put them in the glove box in case it craps out on you. You can make a bad set of points work to get you home but once the electronic ignition is bad, you are SOL.

That is either a myth or an issue that only affected early models of the Pertronix system...I've left my key on plenty of times and never had an issue. Even Ratwell thinks it's dubious.

That said, I would not leave home without a set of points and condenser in my emergency parts stash. As cheap and small as they are, it's good insurance because there is no repairing an electronic ignition module if it goes bad on you.

Heck, I just carry around an extra 010 distributor in the ghia...
The brand I have is Compufire I believe.
They were 1/2 the price of the Pertronix ones and had them for the 2 piece points system disto's. Mine has almost 2 years and 3K miles on it with no issues.
I did buy 2 sets for both the 019 and the 010 I have, but have never installed on the 010.
