How to build a TV Lift cabinet using an off-the-shelf dresser drawers and an off-the-shelf TV Lift Kit from Firgelli Automations. You could easily spend many thousands of dollars on a custom built cabinet with TV Lift, but for about $500. You could spend more, depending on the ready-to-build furnature you buy, but ours was quite inexpensive.
