Yeah, the cheapest one I remember seeing at a show was $150. It was rusty and pretty beat up, but it did work. It was and electric fan driven model and even with the humidity fairly high it was doing a decent job. But then, the guy did have it filled with ICE water.
Watch eBay . . . sometimes you can find some real bargins on off season stuff, so now would be a good time to be shopping. You don't want to try to buy one in August!
I don't know if they still sell them (in fact, I don't know for sure if they are still in business), but Rock Mountian Motorworks did sell a brand new swam cooler for about $450. It looked like the old ones, but it had a paintable plastic housing.
