I tried rechargeable batteries back in 2000, and have not used any since, because they sucked donkey dong through a dirty diaper. But according to all reports (many), times have changed, and the Sanyo Eneloop batteries rock on all fronts, power, speed, holding a charge, and economy. I've already ordered a bunch and a charger. (Amazon UK link.) By the way, I like the kooky but memorable name, and the pleasant and simple design of these batteries.
