They DO exist!! (MSD Opti)
I have never really had any issues other then strange looks Dyno graph;s with running a stock Opti to High RPM. I have been shifting at 7k for years
Now getting them to not burn up the cap and rotor on the other hand HAS been an issue
The adjustment screw is fairly easy to get to with a 6" extension and a swivel socket.
I did end up taking it completely apart, the parts inside are top-notch. It has MSD's own optical pickup in it, and the trigger wheel looks similar to factory, but it's probably MSD's own.
The bearing it rides on is good quality, ABSOLUTELY no side-to-side play like a new factory one.
I'll be sure to keep everyone updated if I have any issues with it!
