Modern Buddy

I saw an older thread, but the Ebayer referenced in it is no longer offering the preferred CDI unit.
Has anyone experience with this model from ScrappyDog?

From their info;
AC operated, spark advanced, no rev limit for GY6 scooter atv 50, 125, 150 engines in 152QMI, 152QMJ, 157QMI, 157QMJ, 139QMB 4strokes.

PGO makes some of the most reliable electronics in the scooter world today, don't mess it up with that crap Chinese CDI.

I was able to get the ones from ebay. While it's a decent setup for good spark, it doesn't really add much other than easy starting. I would save your sheckles.
