Hi, I'm new to the forum & wanted to add to the lift topic. After shopping on & off for over several months, I detemined that a 4 post lift was the one I needed. For the amount of times I will be working under the car as opposed to just needing another parking space, the 4 post made sense for me because of the stability & mobility inside the garage.
I sketched several layouts for another bay, but decided it was cheaper in the long run to go with a lift. My garage has a 12 foot hight ceiling, but with lighting, I have a little less. Clearance is really needed for working under the car so you can stand, but some manufacturers claim a minimum height of 8 feet is all that is needed for parking one car above the other. Of course that depends completely on the car's height, so taking measurements are a good idea.
The least expensive one I found, in terms of the lift price with the shipping fees, was Bend Pak. The one I ordered was this model, a wider than standard one with a 9000 pound rating: (Actually ordered 2 of them)

The dealer I placed my order through was this one, & prices are on the site:

The price
includes the shipping, & I picked it up at a local freight terminal with my car trailer. It can be delivered to you, but in my case I am in a remote location with no access for a Truck. The forklift operator loaded it from the rear of the trailer by lifting the packaged lift from the end.
I haven't installed mine yet, but hope to start this coming weekend. I ordered the drip pans & casters with mine, but decided not to get the jack tray. If I need to raise the car, I'll do it on the floor. I'll post back & let you know how it goes as I put it together. I wanted to do it myself because if something happens with it at a later date, it will be good to know how it comes apart to repair it.
