I'm laughingbecause I just finished mine. Same deal, less than 100 dollars in parts, although I pimped mine up a bit and took more than 3 hours to build. Mine is in a 52 quart igloo coller, with a pep boys heater core(20 bucks) west marine bilge pump(15 bucks) west marine 4" duct fan( another 20 bucks or so) I also wired in two switches, one for the fan, one for pump. Hooks into the cig lighter. Draw is 4.7 amps with fan and pump on at same time. With the free ice from rich guy FBO, mine will last about 1 to 1/2 hour running all the time. Cools the cabin from 95 to 70 in less than ten min. Although it does take up the whole back seat. It does work very well, albeit for a short time. I'm going to experiment with a melody of block ice, free fbo ice, and dry ice on top to see how long that lasts. My friend who I copied from( the most sincere form of flattery) uses a auto power pack, sets it up in his 182, cools the cabin during pre-flight, takes off, climbs. shuts it down at altitude for cruise, the turns it on again for the descent. Somehow a couple of cold ones magically apear at the bottom. In all sincerity though for the do it your selfer it's definiety worth the 100 bucks in parts. If I had paid 500 or so for it I would have been bummed.
