I too just ran into this problem as I have been bowhunting the last ten years, this last year my 7 year old daughter wanted to hunt with me and you know if she goes the wife wanted to go. I built one that was bigger then usual but the design was easy. I used 4x4 post's and just framed it on the posts. I have some pics if you are interested, I too looked at buying one but they were way too expensive for the size I was wanting to get (6X8) box. I built mine complete for aeound 600 and the onesI was looking at buying were 1500-2000.....
