I am very happy with my Big Game Treestands Escape DX. It is of the hub-style design. Basically you pull it out of the bag and then just "pop" each wall (and the ceiling) out. Ready to go. That simple.

I have used several of the Ameristep blinds in the past (Doghouse, Penthouse, etc..). Once you get the folding-together part down they are incredibly easy to use as well.
