I would love to help you but no one could possibly help you with such scant information. I took every possible path with a Thorens TD124 I inherited from my Dad. I had it "restored" by someone who seemed to know how to properly restore it. He did not. I had it set up by someone who seemed to know how to do turntable set-up. He did not. I had a plinth built that seemed beautiful and more than adequate. It was not. None of these people were hacks. They just did mediocre jobs. I found someone who REALLY knew how to restore a TD124 and found a great tonearm that mated well with the TD124 and then found someone who REALLY knew how to do proper TT set-up. I had an incredible plinth built. Only then did everything fall in place.
After having the TD124 restored, I bought the same version of 301 you list and again, it was all about having a true Garrard expert recondition and modify it.
The message I am trying to convey to you is that you with vintage decks you can’t half-ass it. The devil is truly in the details. See my profile and system for pics and details. When properly executed, these two classic drive units can compete with all but the exotic top tier stuff. They have a certain flavor though that is not for all.
As to your question about what price you might be able to sell it for and what you in turn could buy with it, well, that too is impossible without seeing what you have. That 301 if not trashed usually will sell for a minimum of $1,500 but could fetch $3,500-$4,000 if perfectly restored for the drive unit only.
