Looks like Radio Shack has finally caught up with the rest of the world,
and are now offering high-capacity Nickel-Metal-Hydride rechargable
batteries (as opposed to their previous offering of very overpriced and
painfully low capacity ones).
A four-pack of 1600mAh Nickel-Metal-Hydride AA's is $17.99 (I picked up
two). They also have a charger that can fully charge four AA's at a time
in ~1.7 hours, for $27.99. Finally, a reasonable solution for my
juice-hungry TurboExpress!! :)
