I've had a black DS Lite for a few years and it has gone through some heavy usage. The screens, body and slots are fine, it's just the buttons that are a little spotty now. The cross pad is flakier than usual on diagonals and I really have to press some of the action buttons hard to make them work. In your opinion, is it easy/worth repairing or should I just get a whole new console? I'm fairly comfortable with small repairs and have a bit of spare time, but not that much.
