CSG is part of a much larger company that has a strong reputation in other collectibles. I know in the coin world, their sister organization (NGC) is considered one of the grading companies that is well respected. When choosing an alternative to PSA, the years of experience and established reputation in coin grading drew me to CSG. The market will follow. Personally, I'm not concerned about the resale value being compromised because they are not PSA.
However, I keep crow at a low simmer in my crock pot, just in case I need to eat it...
