I have the 65 and couldn't be happier. The only slight negative is the lid doesn't open quite far enough and it tips closed sometimes.
I picked up the wire rack, extra plug and extra hinges as well as the insulated drink thing (bigger one, not the tumbler). Their free shipping and 1/2 the cost of the big brands certainly made it worth the wait. I'll probably grab another one when funds permit.
We took it to Wyoming for August antelope and we came back with the same two ice blocks we left with, they had melted about half way in 10 days in combination with normal ice.
