Looking for a lift!!!

I am looking for a lift as well. (Nice Used Unit Would Be Nice)

This is want I have came up with.

2 Post:
* Are more open and cost less
* Not as safe because vehicle and be pulled off contact points (many photos on line showing so)
* Requires a thicker floor base.
* Need to get down on hand and knees to position lifting arms (Something I do not really want to do as I get older...)
* Not good for storing anothe vehicle on or under
