I use to install Rotary Lifts for a side job when I was still in the USAF. They were pretty nice lifts. We did quite a few at a Rolls Royce Dealer shop and use to replace the old lifts at Western Autos not to mention quite a small shops and home shops. They are fairly easy to install or you can have them installed. But from what I was getting paid by the guy who I helped install them, it is probably not cheap to have them installed.
