portable lifts

I don't have the cieling height for a 2 or 4 post lift, so I was looking into low rise lifts when I found a mid rise sisscor lift by Benpac, it will lift the car about 4' off the ground and is somewhat portable. (weighs 950 lbs) Is any one familiar with these lifts? pros and cons, I know it is a little pricey but free delivery.
