I second what Angus said about 2 post versus 4 post lift in regards to working. I've had two four post lifts and I had the bridge jack, which was a great solution. The advantage to the 4 post lift, for me, was that it is mobile. It does not require being mounted to the floor so if I need to move it over a few feet to adjust things in my garage, I simply put the trolleys on it and roll it around. That doesn't happen often but it does come in handy.
The secondary advantage of the four post lift is long term storage. I don't believe the suspension on my vehicles, and the rubber/silicon bushings, would appreciate long term negative pressure from normal positioning, which would be created by hanging the car from a 2 post lift.
I don't currently have the scissor/bridge jack in my lift so I use jack stands on the floor when needed and lower the car onto them. Makes brake jobs or swapping wheels just as easy.
The four post lift doesn't require any special foundation considerations, like a 2 post.
