I got two of those cheapo knockoffs-AM/FM, flashlight, crank and solar charged-for $10 at Harbor Freight. You can put 2 "AA"s in the back, and I use Ni-Cads from the solar charger on my window sill. It's free energy! The speaker reminds me of the radio I listened to in bed as a kid.
BTW, although Ni-Cads have a few more idiosyncrasies than Nimh, they retain their charge for much longer, so I prefer them. And you can find them at HF, too.
