Aw Bob, there's always room for another Personna thread. I've decided to start referring to the Personna factory in Virginia (Same state as the CIA...Is this a coincidence? I I think not.) as Area 52.
I am staying out of this one. There are plenty of threads about Med Prep vs Blue Labs.
FYI-You can get samplers of both here:
