I had a thread going on this a few weeks back:

http://www.huntingnet.com/forum/tm.aspx?m=3296254

I have updated the content on my web site, took a few more picture and add several tips and hint for improving the cheap River Edge or Comfort Zone tree stands with the small foot space. See this for updated info:

Amoung the improvements:
1) double tree pictue and explained why they are preferred
2) locks for the tree stand
3) carabiner
4) rain and snow

Best Wishes for improving your hunting,
