i got a ‘power station’ today for my wii. it comes with 2 rechargable batteries and a charging dock for 2 wii remotes. i’ll need to get another power station later when i have 4 wii remotes… which might be soon because i already have 3. i ordered it from buy.com. the price is ~$27, plus tax = ~$30, with free shipping, minus $10 for using google checkout for the ‘first’ time, which equals to about $20. btw, i typed this on my ds. :]
