Hello AutoFanatic, we have a good used CEMB DWA1000 alignment machine that is up for sale ... we have used it in our shop and it has worked well ... what we liked about this unit is that it is totally portable ... actually built a bracket system on the wall where all 4 sensors can be easily stored up and out of the way when not in use ... This unit may be a good option for you and i am sure we can save you some cost over new which would be a good way to get you started. Feel free to message for more details or pictures. Will be glad to help.
