I've had enough success with blinds, for turkeys, and just sitting in a chair on the ground without a blind, for deer (or for that matter, just sitting on the ground without a chair), that I've determined tree stands are definitely a luxury, not a necessity. So I won't screw with stands that aren't large & comfortable, like 2-man buddy stands and such.
Funny that Art says turkeys are the best at figuring out "something ain't right".... Art, that may be correct, but I had been under the working assumption that deer were much better at that than turkeys, since I've shot turkeys on several occasions from my blind that wasn't even covered up in any way with sticks and such. I just don't know - may depend on the area - it may be that deer scent me a lot, and I get it in my head that it "must be" the fact that they saw the blind, because I thought I controlled my scent, yada yada. But then again, I've taken one deer from a blind that was just out in the open, uncovered - young dumb doe however.
