This year, we went with a Mossy Oak Gamekeeper 7' elevated metal platform that has a center ladder entry and put a 60" Barronett Big Mike blind on top of it, centered between three pines and a hawthorn in a more open grassy area. That's the third identical setup we have using this system. Up until it really begins to snow, these sets are the cat's meow. A little bit of outdoor carpet and a heater, and Bob's your uncle.
Unfortunately, while the platform was cheap (~$150), I think that it was on closeout from Walmart, and I'm not sure they're available anymore. Also, the blinds, like most blinds in my experience, have a limited shelf life. I may try to put my Double Bull up there next year to see if it is a bit more durable. We have been getting three or four years out of these blinds before they're toast.
We also use reclaimed wood from shipping crates, and it works - but I'm not convinced that they will last. The wood tends to be marginal at best.
