For what it's worth, i bought this setup and was able to align my car over the last week or so. Once I made a few adjustments, I was able to figure out how to get repetitive readings and setup the car. I need to make a slight toe tweak to align the steering wheel, but the initial drive was very good.

For the money invested and how often I will use it, I don't have many complaints. There are a couple of things I would like to improve, but it's a pretty good bank-for-buck. I paid $192 shipped
