I studied the things and settled on the Big Game Luxury Box. I wanted a big platform with a seat that folds up so I can use it for both gun and bow. It also seems to have supports underneath the platform that seems safer and more sturdy.
Finally, I bought two on Amazon for $140 each plus only $10 shipping. That's a savings over most other dealers of $60 plus some amount for shipping.
I will admit, I haven't used them yet, but I wanted to lock in the price.
