I want to buy a ps3 for me now. I have the money to buy a new one. Also there is a guy selling his ps3 at a good price in my town. I was thinking which one should I buy? Is there any harm in buying an old ps3? So, if you were in my place which one would you go for? I know the controllers might be a little old with loose buttons but I can buy new ones from the money left. What do you guys suggest?
