I've been using the $100 Auditorium mat for some time- very worth while upgrade. It's been talked about on here before. You can get it at most WTL dealers.
I've been curious to hear the newer, thicker mat by Auditorium, and Santa baby came thru. Nice thing for many of you without a good dealer for table setup is that this mat is about the same thickness as the stock foam mat, so an easy swap for those of you setup challenged.
Anyway, it's an improvement over even the $100 version, so I'm very very pleased with the results I'm hearing. More see-thru-ness, cleaner bass, and more of that Sam Tellig there there.
Not sure the price, it may have been mentioned on an earlier thread, I think a couple hundred for this one.
Seek it out, it's worth it.
