This may not be exactly what you want, but it is a high-quality table radio with the ability to run on either AC or 12vdc. Price is a little higher than you specified, too.
I have a solar-powered 12v deep-cycle battery on float for use with this radio during power outages. It will run it for weeks during our famous Pacific NW "no sun" winter storms.
