I feel the same way in wanting to see them setup before purchasing one. Then you can compare them side by side with what you like. The Cabela's in lone tree has 4 or 5 different brands and styles setup right now. It made it very clear to me some of the features such as windows, shooting ports, and how they are adjusted. One brand had velcro for the windows. Seriously? My favorite was one offered by Cabelas around $159 regular pricing I believe. It had a unique system to me and was silent. It had a slider system to adjust the windows and screens. It had window openings on all 4 sides which I thought was amazing.

I think you're in the right process and I'd strongly recommend going to seeing them in person. Now is the time of year when a lot of companies should have the blinds setup on display with on weeks before bow season opens. Good luck man.
