There is no better pintrolley that the original one Dad bought from the USA in the 70's. This trolley was used extensively to move Bally bingo games. It has never missed a beat. I also use the Machinery Warehouse trolley. This is different in that the rear 2 wheels are fixed - so it is a little more harder to move games through corners, but it keeps a straight line. I cut a sheet of rubber and glued it to the trolley so machines don't slide. I also have the Gamemaster's Trolley (Greg's) and it is very good quality. I've seen the cheap junk copies, and they don't last long. Often look like they were welded by a child. If you raise them too far, they fold over and catapult the machine.
