I have a 2 post lift installed (and a 4 post). Both installations involved near death experience mainly because I did not have the right tools to stand them up. You really need a fork lift for this kind of job and I was using an engine hoist.
Mine were both very heavy duty American made commercial lifts that I bought used. It was my personal preference over a Chinese made lift as I wanted them to last.
Aside from being very careful, make sure that when you lay down the concrete , you lay it down thick enough to meet the specs on the lift and reinforce it and use 3/4 inch anchor bolts and of course, when ordering check for height clearance. Depending on the design, some have chains that run over the lift or in my case, hydraulic rams which require at least 12-13 ft of ceiling space.

I did use an engine hoist to install a 4 post, the ramps are incredibly heavy, but yes great attention is needed, definitely a 2 man job and no rush, carefully contemplating and planning all moves.
No idea re 2 post but my 4 post works with a garage that has a 3m high ceiling, which is on the low side for any high-roofed cars, but perfect for my SL. I bought it for parking purposes mostly but obviously serves a dual function, so if you might be needing to use it for the former reason too, better a 4 post.

Four posts are different because the cylinder is mounted sideways and the car is picked up at the wheels. With the 2 post, the car is picked up at the sills so extra height is needed in order for someone to stand under them. Some have hydraulic cylinders that are mounted vertically on both sides to raise the lift, they are about the same length as the post so you effectively need double the height.Others use chains to raise the arms, The ones that use chains can either have chains routed over the top of the posts (from one to the other) or under. If over, the towers will need to be taller than the roof line of the car in order to clear. So factor about 12-13 ft when you consider that it should pick up a van and give enough clearance for someone to stand under it.
