Does that say 3 32" rails included? Not going to get very high with that?
Also, I did get a cheap Ameristep lockon a couple years ago (the $50 one). I will say that is the most awful, uncomfortable stand I have ever owned. I almost am afraid to draw in the seated position, it's so flimsy I feel like I'm about to fall constantly. Hope this one is a lot better or it's not worth having.
