Planning on a Shop Lift, Two or Four Post?

[29 Tudor]

I'm planning on ordering a lift for my home shop in the not-too-distant future and I'm looking for recommendations. I have several cars to lift, one of which is my Model A. I'm leaning toward a two post since most all of the use will be for maintenance and repairs. I know it takes TALL lift extensions to get to the A frame but I wonder if anyone has experience with a two post or is a 4 post what most guys use?

Any thoughts and suggestions will be appreciated.
