Have you guys seen this Saskia TT? I don't know how the designer worked the ol' idler technology, but it sure looks booty-ful. 200 lbs. It seems that he makes slate plinths for Garrards, and obviously, a lot of slate used for this TT, too. Wait, I just checked his site & he uses slate for virtually everything!
