This is true, but the Pertronix units are cheap, easy to install, easy to remove and put points back in, and readily available. The downside I've found from them is that their reliability isn't perfect, but they're definitely better than points!

An OEM TFI or HEI is even cheaper and more reliable. If you splice everything with bullet connectors and keep the points coil with you, it's the same thing to go back to points, with no tools.
