CDI or OEM ignition parts, doesnt matter or stick with OEM?

1979 115hp Johnson.

Im working with my motor and debating if I should buy aftermarket parts or stick with OEM. The price difference for the all parts needed is about $70.00.
Is it worth the savings or not?
THis is to replace the fuel pump, 4 coils and two power packs.
Thanks in advance for the help.

The coils and powerpacks are very reliable , not sure why anyone would replace all these parts.----A new diaphragm for the fuel pump is a good idea, rarely do you need to replace an entire pump.------Not many folks replace light bulbs before they pop !------What is your motor doing / not doing .----What trouble shooting has been done ?-----------Nothing wrong with aftermarket on these parts.
