What ignition system will do me justice??

No chance of failure...lol.
Come on man, don't tell me you've never had a condenser short on you. LOL.

The Summit boxes are made by Mallory with some different options to prevent competing directly with them. For my needs, i will be going with the Mallory 685 box as Dusterdon has.

Digital ignitions allow for the use of controls that would not normally be availible without add-on boxes.

If you had two ignition control boxes, one analog and one digital with no options on either, they would function identically assuming the basic components were identical (step up transformer, capacitor, etc.).
