jeff scheck out my current auctions ("psa1") -- I was actually surprised that cards with noticeable back damage got 40s, and ones with lots of damage (though not UGLY damage) got 30s. I've 150% scans of front &back on all of those auctions, so if you're thinking about sending cards in, they may give you an idea of how they'll be graded.
(I'm really not trying to constantly plug my auctions here...just want to help <g>).
