What's the best sounding equipment racks?

I am in the process of building a designated room. Since I am starting fresh, I figured I would replace my Zoethecus equipment racks for a few new ones. From my research, I have found three companies which seemed to shine above the others. Billy bags, symposium and solid steel/rack of silence. I instincts tell me a fully loaded symposium with some the best, but it's cost prohibitive for me. Does anybody have an opinion on the Billy versus solid steel-Rack of silence?
