personal opinion!
someone posted this picture, of a lift,....great impressive shop..but
that looks like an EXCELLENT WAY to have a car pre- set -up too fall off a lift, look at it this way,simple geometry says supporting each corner is far more stabile than ballancing the car fron the center even if the total foot print of the 4 jack stands was only equal to the single lift base, the lift is far less stabile than a quality jack stand placed under each corner of the car and you would be out of your mind to place the car that high on jack stands that are not anchored down,,so why would a lift thats not anchored down and less stable be a good option, one good shove and that cars over on its side, that and the fact theres little or nothing gained in access under the car with that lift, over 4 12 ton jack stands once the tires clear the floor by a few inches, and you can easily use a mechanics creeper to access most of it

at least with these two designs the base is wide enought to be more stabile
