MPRS: Still a useful marker?

  1. Inspired by an earlier posting from Miss Sookie, I'm wondering how helpful y'all think the MPRS stamp is. I have definitely seen some extremely suspicious looking acutions from MPRSs! Thoughts?
  2. There have been lots of threads on this topic already. Maybe you can search and find them.
  3. Any purchases that you make from eBay does not matter who should be authenticated...
