I would like any opinions-positive or negative-about scissor lifts. My shop has nine foot walls, so I don't have room for a two-post. My in-laws live 8 miles away, and they have a two post I can use anytime I need to. But I would really like to have something at home so I can crawl under and change the oil, or lift to be able to rotate tires at home. There are a few interesting ones out there, so would like to hear from those of you who might have one, or have had one in the past.
