Here is my unit, it is still in progress. I built it from 1" square tubing, two 2" square fence posts, rebar, and a 2" angle bracket (the bracket was to level the thing). All in all this cost me under $100; the steel was donated, welder was loaned to me. Second brew on this happening tomorrow, 22 gallon Sierra Nevada Pale Clone. Eventually the cooler will be swapped out for a kettle so I can do steps easier. In a few years I will build a horizontal stand and heat exchange system. Still need a clean pump that can do 10' head pressure so I can pump my liquor into the HLT at the top. This is partial gravity, I must catch the wort and pour into the kettle at the bottom but it keeps the height down and minimizes ladder time. Ladder+gravity+beer+llama=ouch
I have enough issues with flat ground while under the influence.
