Cool Boxes... Anybody have one and how do you like it?

Been kicking around purchasing a Dometic dual zone cool box (Waeco Compressor) unit for the backseat of the pickup and for the wife to keep refrigerated foods in when she's going shopping to keep them frozen or chilled.

Several good brands on the market, all with compressors of different designs, Waeco, Danfoss and Panasonic

Whats best and what works for you?

Time to loose the ice chest for good.
