[mrmopar]

I'd rather have a small flaw on the back if the front was nice and I don't really deal that much in really expensive or rare cards, so preferably most of my cards are not going to have any serious flaws that hurt the eye appeal.

However, for something very old, rare and/or expensive, I could live with a back flaw that kept the price within reach.

Not quite a perfect example, but I did buy a 33 Goudey Ruth with a small pinhole in it because I have always wanted that card but couldn't justify spending the money that a clean copy of similar condition would have cost me. The pinhole bothers me some because you can't miss it, but it is small and the rest of the card looks great otherwise. I was able to get it in my $ comfort zone as well.
