I just bought this and its great. Designed specifically for Pinball tables. It fits right under the tables and has one lift setting that rises the machine about 6 inches off the ground. Its shaped perfectly for tables and allows easy transport or leg work. It also weights significant less that the standard hydraulic tables. This price on Ebay is the best I have found and my experience with twisted quarter was great. Good communication and they shipped it promptly and well packed.
