Despite using rechargeable batteries (double a), I am think of getting a charging station, which should I get? As to why I want this . . . the batteries I have now don't seem to always fully charge when I put them in the charger. As I also have wii-fit, the amount of batteries I have for 2 wiimotes (might get more later) and the board would seem to go quickly. -- Also is there a set of batteries for the wii fit board?
