I also got sick of buying AA batteries, 'cause I take THOUSANDS of pictures on every vacation. So, last year I found a Duracell 1 hour charger that came with 4 rechargable batteries. The great thing about the one I bought is that it not only came with a wall plug, but came with a car charger, too! So now I can charge batteries on the go! The charger & 4 batteries was around $20, and the extra set was around $12? I think I found them at
Walmart or Target. I just throw the whole thing in my camera bag, and the camera bag goes with me everywhere!
