I think a lot depends on when it was made...supposedly their are some "potted" units (2004 sticks in my mind) that can't be repaired, but I've always heard that if you send what you believe is a "bad" unit to MSD to check that you'll get it back labeled as "nothing wrong" but that they're often fixed without mentioning any problems/repairs/costs. I've never done this, but have heard this for several years now...
EZ: what about the Digi6s? I've got an early Digi6 that I've ran for several years that I bought because it was cheaper in the long run once you bought an AL6+retard+limiter...

I bet most of the parts between the k66 and MSD could be swapped and still work...they're both trigger driven cdi setups essentially. I've used an MSD reluctor wheel and a stock Chrysler hei reluctor wheel in otherwise stock GM dizzys to trigger an MSD. Some of the Mopar guys in the Pure Stock class gripe about the Chevys getting to upgrade their points to a better ignition setup, but I always tell them several of the GM cars could go k66 *legally* and basically be running MSDs.
