Millsy, yeh i know what u mean. Most like that, and the one I had custom made, dont lift up high enough. I will take a photo of the black one I have. It lifts just high enough to take legs off, and does fit between the front legs on all pinballs, but its only good to move short distances.
Overall, the pinball skates that ANT68 sells on ebay, are the best to move machines in and around the house etc, even up n down driveways, but the lifter types are the best to get on and off the ute etc.
The link for Tonys (ANT68 - member here) pinball skates is below, and a good price for $95. I have at least half a dozen sets of those and they are excellent.
