All I have are home made. I own my own land, so I dont have to worry about moveing them or other people screwing with them. I simply get 1 inch square tube. You can get it at a metal store, it runs about 15 bucks for a 25' joint, primed. I just set in my shop with my chop saw and welder and make them how ever I want. I use 3/4 inch ply wood to make my seat. They work great, and you can make a stand for about 15 bucks each. There are so many ways to make them, let you imagination run wild. You will be surprised at how many ways you will come up with.
