I bought a Avery Finisher a few months ago, haven't used it in the field yet but I mudded it up. The Finisher will work great for me, easy to set up in the dark I don't have any complants. I also heard great things about the other two you mentioned the Cabelas and the Power Hunter. I haven't heard of any complaints about visibility problems with the Power Hunter. Any one of the three you mentioned you can't go wrong. I'm sure the Cabelas blind is cheaper I believe $160 not sure about the durability. Good Luck.
Just because it is old dosen't make it a classic
