An old thread, but not sure if still need info for owners re trolleys. Bought the red one with chrome handle, and works a treat on both standard and wide body machines. now costs $275 from Coopers Plains in Brisbane.

Yeah I bought one of these too for $210 from General Tools.
Great trolley but the only problem is that you can get it far enough under the machine from the front, some machines are too back heavy and the trolley doesn't lift the back.
It will be fine though once I make a bracket to angle the handle.
