I would buy a 2 post, more useful, they can be used for simple things, like picking a bed up on a truck to remove the fuel pump.
Local friend of mine, has nice garage which he makes a living out of, business licence, been doing it for years.
His 4-post lift broke a cable with a car on it, he got the car off with no issues, but the replacement cables for the 4-post was over $2000, he junked the lift and bought a 2 post.
He hauled the 4-post to the junkyard, in hindsight, I should have got it off him and fixed it.
