Dtc, you could be right, although I never heard anything about manufacturing problems with the 100% acrylic platter.
From the VPI website - The Super Platter is no longer being produced by VPI. It was excessively difficult to make, had issues with stability of the three layers, and could never be machined as accurately as the Classic Aluminum Platter. The Classic Aluminum Platter replaced it and is a better running design.
