I have the Tecsun Green 88 which appears to be the OEM version of the Grundig FR200. Its a nice radio with a choice of power sources. The flashlight is handy to have, but the dial isn't illuminated. Can't have everything I guess. I also found it tricky to tune to SW stations which are close together. Took quite a bit of fiddling with the fine knob.

The Nicd battery looks like the type you find in some cordless phones and you can run off 3 AAs and wall wart as well(not included). The Nicd battery got really warm after a few hours with the wall wart plugged in, so I wouldn't leave it plugged in as standby.

An alternative would be to rely on rechargeable AA by solar power as suggested by Les above.

I've been thinking about the TECSUN PL-380 DSP radio as its rechargeable via USB, and auto and solar USB chargers are becoming common. I have the Joos Orange charger which I like a lot.
