Another one to look at is the Grizzly. We carry them in our archery shop. They are about 20% cheaper than the Yeti and they are more accurate on their quart size than Yeti.
There are a few tricks I have learned for all the people that doubt these type of coolers. They hold heat just like they hold cold. So if yours is sitting outside in the backing sun with nothing in it and you just open it up, throw drinks in it, and throw ice it in you aren't going to get very good results because you have basically a hot cooler trying to hold that heat in and the ice isn't going to last long. If nothing else open it up and bring it inside your house for a few hours to cool it off. Or what we do is fill it up outside with cold well water and let that water cool the cooler down before loading it up.
