As promised, pictures of the lifts I use:

12,000 lb, 2 post, side by side, in ground. As I said, when I priced this a few years back, it was $2500 installed. http://www.bunchobikes.com/lift1.jpg

60,000 lb, 2 post, in ground. http://www.bunchobikes.com/lift2.jpg

75,000 lb, cantilever. This has a double jack that rolls on the rails under the lights. This way you can lift an axle and remove wheels.
