Query: Charge Station

This charge station from Nyko works great. Replacing batteries can get expensive fast...and it's not green. These hold a charge for days and recharge fast. The only slightly negatve aspect to this device is the charge base emits a barely audible 'beep..beep..beep'. One night, it took me 45 minutes to figure out WTF it was. Way worth the 30 clams.
