Very nice unit, easy to hook up, saves $$ and keeps the nearly bulletproof 7AL2 as the main ignition. No sense getting rid of a perfectly good box, even though MSD would rather sell you a Digital-7, which is probably why they never talk about the #8979.

What are the real advantages of the digital conversion. I have the old reliable 7AL-2. I havent really thought about converting because of the cost. Is it really the way to go?
