I bought a 3-man Eskimo pop-open style for around $200 at Marine General in Duluth, MN. Suckers here in Canada wanted over $400 for it
. I like it, but be sure to bring a tie-down rope for the windward size. The huts are sturdy so much so that if you don't anchor down the windward size, your hut may get lifted right up off the ice and carried down the lake. The four anchor srews can only hold so much when a good gust of wind comes up!
