do you people think its really worth the money to buy one of these things?

well if you still have your ps2 games and still play them and need the saved game on your memory card well then yes i think its worth it.

Ehh. not really worth it, but if you need it, you need it
The only reason why you would need one is when you play PS2 games on the PS3 though.

But they're not cheap, the lowest I've seen them is $23.xx shipped at http://us.emvee.ca/

They cost like $15 in the store and like I said before: I bought it, used it, put in back in the box, returned it.
