I had looked in to getting a high end cooler this summer. Never could justify one for my use, but Sams club has the Igloo Sportsman 20 and 55 qt roto molded coolers. The one in Aurora had some a month or so ago. The 55qt is $200, which is significantly less than a pelican or yeti of the same size.
They felt decently built. Not as well built as the pelican I handled though. When I was standing in Sams club trying to decide if I was going to buy it, I was honestly thinking to myself that for $200 I wanted better quality.
FYI walmart was carrying 65qt pelicans earlier this year. I've seen forum posts where they weren't moving so Walmart marked them down to less than $200.
