Summit Viper all the way! Maybe a Goliath if you are over 300lbs. Light, Comforatable, faster to set up than some others and a great value for the money. I had a API and a cheaper steel wal mart special ($60 ten years ago).
Dont be cheap and buy a 35lb steel stand. Aluminum is much nicer to tote through the woods.
To me it is the most essential piece of hunting gear I own besides the weapon for hunting public land. I take naps in mine if I get out really early in the afternoon.
