Tom,
this may not help you immediately but there is a great book out there that was intended to be a refutation of the KJV-Only position but is in actuality a really good overview of this very issue...manuscripts, what's the difference, why does it matter, the real skinny on all of this.

It's called "The King James only Controversy" by Dr. James White.

I highly recommend it.


Aside from that, in answer to your question; here is the split;

TR - King James, New King James

Alexandrian - All other bibles


I HEARD that there might be a new translation coming out based on the TR but I don't know.
