In my experience, the grading guarantees are for real. I've purchased a card that SGC graded a 3 (VG). In the auction, the back scan wasn't clear, and when I received it, there was scrapbook residue on back. I sent it back to SGC, and it came back at 1.5 (Fair). SGC refunded me with a check and some grading credits which I thought was very fair, and I was very satisfied with.
For Beckett, they holdered a photo that was determined to be counterfeit. They sent me a check to fully compensate me for this. Again, I thought they were very fair and i was very satisfied with the final settlement.
I haven't tried PSA before, so no experience there.
