I just bought an ozark expedition 52 qt cooler at walmart. It's basically a Yeti rip-off, roto-mold cooler. I paid 147.00. It seems to be built to last a lifetime (kept out of the sun). While this seems pricy it is cheap compared to yeti at around 400.00. Looking at this site/thread Ozark Trail "High Performance" cooler - any good? - Expedition Portal where comparison tests were done, it looks like it goes above and beyond it's rated 7 day ice holding capabilities. I'm going to need this for my first week long remote camping.
