What kind of turntable do you have? What kind of platter does it have? Why do you think you need a different mat? What are you expecting the new mat to do?
Most of my tables have acrylic platters and I use a clamp or weight and no mat. I have a couple of DD tables with metal platters and find that the mats that came with them work fine. I've tried cork and also some deer skin mats. The cork was good, the deer skin seemed to quiet things down and help with static, but also took some of the life of the music away. In the end, I'm not using either.
That's why all the questions above. Maybe you already have things set up well and don't need to change anything.
