I built my own with two cheap craftsmen cabinets back to back. Over the years the drawer slides are wearing out, and i would definetly get ball bearing slidesinstead. It measures about 4 ft X 4 ft X 4.5 ft tall, and I put big casters on it. Trouble is, I am always roling it out of the way. So, next I bought 4 3 drawer rubbermaid drawers from menards and put them against the wall, and on top of those I put 4 3 drawer Clarke tool chests for the small hand tools. Then on top of all that I have a counter top. The whole thing is about 9 ft wide 4.5 ft tall and I have room for tons of stuff. and it is always in the same spot and not in the way. The large drawers from rubbermaid hold all the larger stuff like drills, hammers tape measures, pry bars, socket sets, tape, flash lights, etc. each thing has its own drawer. The only rolling cart I want now is a small tray that i can put stuff on while i am working on something. .02$
