PSN Chinatown Wars PSP For $5 Worth It?

On PSN right now Chinatown Wars for the PSP is $5, is it worth it?
I owned it for the DS a while ago and loved it, but heard the PSP version played better in the action scenes and looked better graphically, BUT the DS version controlled better during the minigames.

So, is it worth picking up?

If you liked it enough to want to play again, then it should be worth $5.  I've played the PSP version, but not the DS version.  I liked the game except for the hot wiring a car mini game.  Consequently, I would so much rather car jack somebody than steal a parked car.
