I have this one .

I got it for about $350 as a factory-reconditioned model from the manufacturer\'s website .

A friend of mine uses a much smaller Waeco model as a freezer, in which he stores frozen water bottles and other frozen foods. He then transfers the water bottles to a standard large ice chest to keep his food cool. As the water melts, he just trades them for frozen ones. In doing this he is always able to have both frozen and refrigerated foods during extended camping trips.
