Just to add to this some more.

I have read many many more reports of MSD/Accel units failing either right out of the box or after a few miles. Many more than non-factory installed GM units.

I know MSD had a few issues when the first released there product and I think for the most part they are pretty good now a days, but for the price you pay... is it worth it?

I think many people attribute their mistake of getting the opti soaked or similar to the GM unit being garbage. Mine was 100% fine for 75k miles and I replaced it for piece of mind when I swapped cams. I got a new GM unit, and it is doing 100% fine.

I guess to each his own, but I could not justify spending the money MSD wants when a GM unit is much cheaper and has a much better track record.
