I just bought two fake "buckstep" units from the local gander mountian. While not necessarly as light, they were only $11.99 on sale a piece there.

I tried them out on a tree in my front yard when I got home, and they work very well. They have a 1" strap which seems to really dig in to the tree and no-skid on the steps. I'll try to post some pictures when I get them up for good.

While they aren't as light as the bucksteps from summit, I was mainly planning on taking them out at the beginning of the season and maybe moving them a couple times. I'm not going to switch trees too often -- that's what a climber is for.

So far, the first impression is that they are sturdy and well made. I think I'l go back and get a couple more this evening.
