I have the max-jax two post lift. My garage is low clearance made worse by heating ducts and garage door hardware (need to replace with a jackshaft opener).
I have an older home and the concrete was just below the minimum thickness and no rebar so I made a complete mess and saw-cut the cement, dug out the hole far deeper than required, made rebar cages that are epoxied into the existing pad and then mixed and poured the cement. A bigger job than expected, but happy with the lift set-up. When I move again I plan to move to a four-post lift. When I was still working our fleet shop had a mix of two and four post lifts and I really enjoyed working on the four post. All of those had a front and rear bridge jack so it was easy to lift from underneath when needed.
