The coleman xtreme is a great little cooler. Walmart sells them cheap, and in the summer Costco has the marine version (white with stainless hinges) for just a couple bucks more. May be able to get it on their site outside of summer, I don't know.
When shopping, you can all but disregard ice retaining claims. To get those numbers they pre-chill the coolers and then fill the cooler to the brim with ice, and leave it in a room, not outside, not in a car. Unless you're using the cooler to transport ice, those numbers don't matter to you.
The biggest learning point for my coolering (sick verb, bro) experience is that air in your cooler is the enemy of holding ice. You want that thing PACKED, and you do NOT want to drain the water. Even if the water is warmer than the ice, it's cooler than the air in the cooler.
With that little tidbit of knowledge I went from a very disappointed Pelican ProGear 65qt cooler owner to a very satisfied owner.
I now pack the bottom w/ canned/bottled beverages (standing, not just thrown in there), then pour a bag of ice over those. I have two of
these pan things that fit perfectly in my cooler and take up about half of the top of it. Inside of them I'll put anything I don't want to get wet. The other half of the top I'll put the big stuff... Gallon of water (lol, jk, gallon of vodka and juice) and the like, then I'll pour a bit more ice on that side. With all of that packed I am left with about 1-2" of air under the trays, and I can live with that. If I want (need) beer, I can simply pick the tray up and grab one (two).
Here's a picture from Amazon of how that tray fits in the Pelican 65qt...
Here's my cooler... I upgraded after a long weekend of buying 5-10lbs of ice each day for my Coleman in 100+ degree heat. Even [MENTION=82154]GSPRunner[/MENTION]'s Yeti 110 was struggling to hold ice in the sauna that was the Northwest Overland Rally.
