Re: the Coleman cooler from Wal-Mart. When our original B&D cooler died last month (after quite a few years of service), we tried a Coleman from Wal-Mart (no idea if it is the same model that Westfield is referring to)... it was SO LOUD and the sound was at a pitch that really bothered me. We wound up taking it back and getting another B&D just like the original one... much quieter (and smaller than the Coleman).
So, if you do get one of the small portable units, be sure you can live with the sound it makes, especially if it rides right behind you in the truck. :wink:
Best wishes,
