We used an INCA slide and rotate surface to move a 35" tube TV out of a cabinet and rotate it into place. It was precise in its action. It was also something like $3000. I'd do it again, but I also live close enough to INCA to go there and look at the shop and the parts to be used. (INCA, if you're reading this, the idea of painting the walls of a metal shop bright yellow, which highlights the incredible cleanliness of your entire shop, is a genius move!)
