I have the Bendpak Mid-Rise Scissor lift and love it. I was tired of being on my back since I do have back problems. I wanted to get a 4 post lift, but my garage wasn't big enough. I looked at the Quick Jack and the like, but they didn't go up high enough. I think this is the best alternative to both those options. The build quality is as good as you can find and I never feel unsafe underneath it. Plus, it lifts and retracts very quickly. It is more than your budget, but I think for the quality and portability, it was worth it for me.
