For what it's worth, I have not liked acrylic mats or platters in the past, but probably that's just me. The only platter per se that meets your criterion pretty well, Ralph, is one of the several options offered by Thom Mackris on his Galibier turntables. It may be made of Delrin, but I cannot recall.
Nandric, Try getting loaded on slivovitz instead of acrylic. Acrylic is bad for the liver.
