I have a forward brand, two post, ALI certified, made in the USA, lift and I love it. I do a fair amount of work that makes the two post ideal (removing engine from below, trans, etc).
As far as bending over to place the arms...If you are doing this for your own vehicles, the answer is pretty simple. Draw or tape some parallel lines on the floor. Pull your vehicle in to a designated stop line. Use a mirror or helper to get the vehicle in the same spot every time. Place the arms where they need to be. Mark the angle and length with a permanent marker on the arms. You can now replicate this forever. I have two daily drivers marked on my lift. Pull up, push the arms in with my foot (don't even have to bend over), raise the lift 2-3 feet, check placement, and raise. I can have my 2 cars in the air in a matter of a couple minutes.
My Corvette is a bit more work. It's so low, I have to pull in, jack each side a couple inches, place one arm, remove jack, place second arm, and repeat for the other side. Some day I'm going to figure out an easier way!
