I don't like PSA and with SGC grading autographs now (I'm assuming) I think the superior slabs and easier customer service that SGC provides will allow them to steal a good amount of PSA's business in 50-60's auto'd cards.
I've been slowly grading all of my modern Utley Ginter cards with SGC. One of my favorite cards that I own is a 98 Ginter Cabinet /25. My grades actually just popped tonight. Some as expected, some not
edit to add scan.
I think the modern cards based on vintage sets look great in SGC holders
