Right. It can take hours, sometimes more than two, to set up a turntable for the first time. Doing this can void your ability to be helplessly dependent on sales and service. Don't fall prey to charlatans trying to sell you on the simplicity of turning a screw. Only with highly specialized training and years of experience can one operate a level.

Its simply not worth it.
