Well, the CDI box on my banshee finally fizzled out. Had to cut loose $400.00 for a new one

For that price they must have a Pentium 5 processor and other super complex computer stuff inside. I wish the ignition on my bike were as simple as my chain saw where a small magnet mounted to the flywheel swings past a coil , creates a spark, and runs fine. But not the banshee, Nnoooo Noooo Nooooooo.
Does anyone know of another after market brand that's built to last ? I'd like to completely replace my whole ignition system someday. Thanx.
