Ok, I will give you my opinion, I have used Ameristep, Double Bull Tall Model, and Eastman Outdoors. Without a doubt double bull is the best, but at $400 it should be. All have great customer service, if a pole breaks call the company and they will send you a new pole. I was at Sams yesterday and they have an eastman for 150 that is the size of a small garage.
With my double bull I put it out the first week of season 2 years ago, within one week field mice had eaten the entire bottom, (I assume field mice, I actually never saw them) I left it out the entire season after that, rain, sleet, snow etc. I sent it to Double Bull after season and they repaired it for I think $125.
From what I can tell, Turkeys don't care what blind you are sitting in as long as you can shoot your bow out of. The other thing I have noticed, is whiteails in MO you have to brush it in so much they don't care what kind of blind it is either, just as long as you can shoot your bow out of it.
currently I have 2 ameristep choice blinds, I can shoot my 62" recurve out of it, if I am in the back corner.
