Etón FR500 Solarlink Radio  What good is going off the grid if you can't keep up on the Mets? That seems to be the premise behind Etón's line of rough-duty radios. As its name implies, the new Solarlink is powered by the sun (or, during a nuclear winter, a hand crank). It comes with a flashlight, emergency siren, and—should you need to get back on the grid—a charger for cell phones and MP3 players.  $80,  etoncorp.com
