[SIZE=2]For the memory card I would definitely stick with the Sony cards.Sony has revoked the license for all third party card manufacturers due to the lack of quality that was found in most.
For controllers I found the Mad Catz Dual Force 2 to be a good choice-it is a bit bigger and has a macro command button (handy for that long combo on the fighting games).The sticks are a bit looser compared to the Sony controllers but still work well.Just don't let it drop to the floor-they can damage easily that way.[/SIZE]
