Another vote for Pertronix here. I've had it a couple of years now and, along with the ease of installation, the difference in how the engine runs makes me think it's a great "performance for the buck" option. I've heard some have problems with it which, from what I've heard them describe, are pretty much related to overheating and/or leaving the ignition switch in the "on" position too long. This last is apparently a problem with the original version but the newest incarnation of the device is advertised as not being susceptible to that problem. I keep my old points, etc. in the glove box in case the Pertronix module craps out on me, but it's been so long since I've changed points now, I'm not sure I'd be able to reinstall them without a manual. ;D
