I'm a fan of the ones Shrapnel found.
His six cost about the same as the one I bought many years ago that still gets used.
I may look into a Lifetime one someday, but for now, with the Coleman and a couple of Igloos I'm pretty well set.
SamO, good luck finding what you need. Me, I get by for a day with an El Cheapo one and a frozen 1/2 gallon milk jug of water. Keeps my lunch cold enough for me.
