I would buy it. Its a Rotary, that is one of the best brands out there. I serviced and installed these for years when I was younger, and that was "the brand" to have. I looked for a long time for a Rotary before settling on a BenWil.
I don't mind putting a car on a two post. But it works better for what I do. I mostly do suspension, and have the wheels off, so a drive on wouldn't work. Space is also cramped, and a 4 post is just much too big to allow cars to get in and out of the back of the shop.
