What are the better rotomold coolers today? I have seen some at Sam's Club that I think were Igloo made. I also wonder about brands like Orca and RTIC. What is good in a ~30qt size for the money? I'm initially thinking Engel Deep Blue 35qt but, wonder about others in the $150~$200 range that have a lot of insulation and are not the cheap flimsy "walmart" 5-day variety that fails too quickly.
