That looks like a painters, sheet rockers scaffolding with tier steps added.
Looks great vs those 2" x 2" 1/4" wall thickness all stainless school bus lift stands I have seen built. My winery lab worker makes the best homebrews out of plastic buckets and laughs afte seeing the over the top price systems manufactures have on the market besides what he has seen on brew forum brewing systems members have cone up with.
Overall I see this as a big market rather high production item, there are many homebrewers around the world. I do not buy that low production answer causing the high costs. Highly skilled workers, one good Tig welder working full time and an electrician ot someone who can follow wire colors being cheap labor english not required. When there is a demand for an item that the general public can not manufacture by themselves they the manufactures can ask those crazy high prices and get it. It's a item many people want that may not have the ability alone the equipment to build their own brewing systems hence they have to buy the "got ya" price. Unless you already have a Tig machine, band saws, chop saws, (cold saw would be great), plasma cutter, grinders and the ability to use the equipment then the only costs would be fitting, pumps, temp probes, plumbing, must add painting unless only powder coating a must have finish item and the heat source equipment of your choice. Labors free but the love of building a brewing system to your own design, this alone is priceless. This how I see it after working in different manufacturing plants for 30 years as a electrican. Front office area a college educated person or the engineers in a room nearby,in the back working assembly area a room full of non speaking cheap labor workers. I have worked in many building seeing this over and over first hand. This is not in the sticks but around the San Francisco bay area. Sorry I had to chime in on this one.
