I have a mid-rise scissors lift set up, and I rarely use it. I've got it bolted to the floor but it still feels unsteady. I think it should be anchored in footings to be really sturdy. Plus, the structure of the lift leaves little room to access much of the underside of the car. It has only one hydraulic cylinder, which creates part of the access problem. Can't tell you the brand, as it's actually my brother-in-law's, on permanent loan from when he was cleaning out his garage.
I prefer the Kwik Lift I bought used several years ago. It supports the car level about 20 inches off the ground, providing about 28 inches of workspace under the chassis. It also has a jack platform so you can set the car on stands while it's on the lift, so you can pull the wheels to work on suspension, brakes, etc. On concrete the car is rock steady while elevated.
Here are some photos of the Kwik Lift in use.
