I am finally breaking down and buying a 105 qt Yeti this weekend. I can tell you that I think it is still too small a space for too big a price- but, I love to cook and I hate it when food goes bad.
So, after spending a year looking at coolers, I say look at the Gott Marine coolers from Rubbermaid- not the new ones, the old ones- they are still on their website. They don't make them anymore I guess, but they were ideal in several ways: maximum cooling performance for having a smaller difference in ratio between inside and outside dimensions, re-freezable water bottles that fit snugly inside the cooler and into the lid, solid construction, and a much lower price.
I've seen only one in action, but it worked as well as the big names- on day 8 in 100 + heat, we still had ice for cocktails.
