Eneloop FTW. I'm in the process of replacing every battery I have with Eneloops. They work amazingly, last forever, can be recharged around 1000 times, and in the long run are MUCH cheaper if you go through a lot of batteries like me. Not to mention the "green" benefits. Unless I'm in some kind of a bind where I need to grab whatever is on hand, I don't see myself ever using anything else. Alkaline is a part of the past IMO and don't ever intend to look back.
