What a shame. Almost sounds as if the people shipping didn't take the platter out?
I took no chances with mine. Actually drove 1.200 kilometers roundtrip through three (!) countries to pick it up. Placed it in the back seat with additional cushioning after having taken out the platter and adding bubblewrap around the arms.
I've already been informed that I should look out for a good spare-parts Bg4000 to keep on hand - from this thread that sounds increasingly difficult!
