I agonized over this decision. I checked out Bend Pak, AC, ProPark, and Rotary/Revolution. Most people in the "business" including my mechanic recommended Rotary/Revolution as the one to get. They are at least $1000 more than any other residential lift but I needed convincing that it was a thousand dollar better lift than the others. Then I checked the shipping weight of all the lifts I was comparing and the Rotary was 600 pounds heavier than the closest other lift. That must say something about the quality and guage of steel and materials used in this lift. So I bit the bullet and got the Rotary (It's due to be installed in February). I figured for the extra grand, I feel more secure.
