Wireless mouse & keyboard Q

[tygerbryght]

I recently went wireless (and am still having problems with the repreat rate on the KB).

I love it, mostly, but I've decided the learning curve on the mouse is a lot steeper - I keep having problems I wasn't able to anticipate. The one I need feedback on is batteries. The cheap, never-heard-of-it brand batteries are already history, but I just had to change the Coppertops I installed in the mouse only last week. Is this typical?

Do I need to start buying AAA batteries by the gross?

I don't like the disposal issues with batteries, so if that's the case, can anyone make recommendations about rechargers?
