CDI Units

I seem to be going through a CDI unit a year on all of my scooters... intermittent problems.
Whats the preferred Brand... I've tried BGM, Ducati, Cheap Shit Blue ones etc... all seem to be the same.
Ironically it always used to be that Ducati were the preferred... but Ducati motorbikes are famed for their electrical issues...
