I put two Boss blinds on a place I take care of. They are nice in that they seal up good and look good. They looked to be the best bang for the buck blinds I found. If you get them make sure you get it fully carpeted with a shelf under all the windows.
I did add a piece of 3/4 plywood to the floor. It made me a little nervouse when bolting the fiberglass to the towers. Now the fg floor is bolted in between the pw and metal.
