How much is the turntable worth? For instance, If it is $15K I don’t think it is worth it. It depends also on your personality.
I have purchased solid state electronics from Germany. I bought a CD player from Canada and over ten years had to send it back three times for repair. For me, I draw the line at mechanical. I would prefer to have local representation if mechanics are involved.
My rule of thumb is, if the transaction is a complete disaster and I loose it all and I can say, “oops, a learning moment” and move on without regret then I’ll do it. There is enough stress in my life, don’t need to add more.
Typically the reason you save the money on buying on the gray market is you loose the warrantee.
It sounds like a legit dealer and the only likely problem is if there is a defect, or it is damaged somehow. Turntables are delicate instruments. Now, this is me… I don’t mess with them. For the last thirty years I have owned audiophile turntables. I don’t mess with them. I am a klutz, I do not have a great deal of patience… so I know myself. I have a dealer… he comes to my house to fiddle with it. If I lived in the middle of nowhere and wanted a TT, I would take a trip (500 miles if required) to a dealer.
