If you've never worked on a vehicle on a lift, especially a 4 post, then I suggest you find a friend or somewhere you can use one for a few different jobs first.
I worked in a shop with a 2 post and a 4 post and the 4 post got used primarily for storing another vehicle, none of us liked it much for working on, it seemed to always be more or less in the way for whatever you were trying to work on.
A 2 post lift has very little in the way while working on the vehicle either lowered or raised, and very little of the lift in the way in the shop with or without a vehicle on it.
Don't buy a lift on looks and ideas, try some out for real before deciding what type you like.
