You have several choices. Do you want to have a complete electronic conversion that will eliminate the ignition points and the mechanical advance. The hottest stuff has most recently been the conversion to crank mounted electronic conversions. You can have a Hall sensor to eliminate the points but keep the mechanical advance. Or you can keep the OEM stock system but take the high Voltage pressure off the system by incorporating a Booster.
The most expensive is the crank mounted systems, around $500, and the cheapest are the stock system with a Booster, about $80.
I'm a fan of the Booster. The points are kept in place but should last many years with occasional checking and adjusting. If the Booster fails the OEM set up can be reverted to and only needs moving a couple of wires.
There are many adamant fans of any of the other systems also.
