Some our favorites are the Gorilla (the biggest one they sell) which were purchased at Walmart after the season for $40 each. We also use a bunch of Big-Game stands that are rather large, and have a curved up foot rest on the edge (they arenice since you know where the edge is at all times, they also have very nice harnesses that come with it). The Big-game also have a metal mesh seat that can be used without a cusshion. Both of the stands are rather lite. We also use a bunch of ladders.

For my climber I use a Lone Wolf (not the sit and stand model).
