I've converted from points to electronic ignition several times. Mercruiser Thunderbolt (expensive but can purchase used off ebay); Mallory (cheapest and easiest) and MSD. I liked the MSD the best for performance but all things considered would stick with the Thunderbolt. If you do go Thunderbolt make sure you get the right part number for the ignition amplifier as the advance curves differ by engine and horsepower.
