It's far too new at this point. Particularly in the case of PS3 exclusives, it's harder to find a good price. (inFAMOUS is still valued at $25, and Uncharted 2 is still in the $40 range.)
I wish I could help, but you might want to give Indigo Prophecy/Fahrenheit to see how David Cage can Direct and Write. (I have to warn you, he's not amazing.)
If only I didn't enjoy gimmicky gameplay.
