I just bought one of those dollies earlier today. I also bought two extra caster wheels to put in the middle of the dolly to dramatically increase its load carrying capacity. Once I build a stronger platform from some 2 X 12s, my new Sunnen hone (close to 1000 pounds) will be able to be rolled around the shop floor and stored in a corner when not in use.
