@travisg Congrats on your new table. I loved (and still love) my VPI Classic 3 even though my primary rig now uses a Clearaudio Innovation Wood. +1 to gjohns and invest in the outer ring when ready. Also consider getting Isoacoustics Gaia II footers for the table and replace the stock feet. They gave me a worthy upgrade in imaging clarity.
Also, your preferences may differ, but I found that the best mat is no mat. I loved playing records directly on the aluminum platter, especially coupled with the ring clamp.
Enjoy!
