For $20, we offer console appraisals. During the appraisal, we due any minor repairs (e.g. fixing loose wire, reseating loose components, and cleaning out dust), and diagnose any more significant problems with the system. After we are finished the appraisal, we contact you and let you know what is wrong and how much the repairs will cost. We do not do any further work on the console until we know whether or not you would like to go ahead with the repairs.
