Unfortunately, too much experience with this stuff.

For my car, there are three alternatives. Pertronix, Crane/Allison and Lumenition. All use a trigger wheel, the Crane and Lumenition also have an ancillary small power box that the Pertronix does not have.

Of the three, I have found the Pertronix to be the most reliable, the Crane second (it was on the car when I bought it and failed) and Lumenition unknown as I just bought a couple of units to try.

You probably have options as well.
