These are the best designed carts I've seen:

AT $2800 USD they darn well better be. My R&R was like $125 when I bought it. Just used it again yesterday. I can load over 200 Kg on it and it's still easy to push and control (as long as where it's going is flat!).
The Inovativ carts are precision machines, the R&R is stamped and bent steel. But I'm just hauling stuff, not building a workstation, so the R&R is just what I'm looking for.
