Optispark crapping out

So we figured out the optispark is causing all the problems on my car. The only question now is, MSD or GM replacement. I talked to thunder racing about the problems with msd rotors coming off and was told that if you make sure the screw for the rotor has loctite on it then there will be no problem. My question is, from personal experience would you recommend a MSD or a GM performance parts?

I've never had one..a friend did. Junk.

Do a search and look at all the threads. I wouldn't spend my money in something that has no advantages over stock and cost $500!

JMHO...
