I don't want to be accused of "scamming AG for a free ad".
As I said above, the devil is in the details.
Was your motor truly torn down piece by piece and rebuilt by someone who knows how to make it "new"? Was it rebuilt with upgraded parts such as this https://www.classichifi-shop.co.uk/product/garrard-301-uprated-brass-spindle/ ?
I will drop two names for you to consider consulting-Greg Metz (outside of Nashville) and Steve Dobbins (Xact Audio). I will warn you that neither are arse-kissers; they will tell you what they really think and in rather succinct fashion. What they can both do is lead you to where you want to be. Greg is the guru of rebuilding motors and all associated parts, Steve is the expert on plinths, platters, and mating the 301 with a complimentary tonearm.
