Dave, I have two ROK's at home. One in a heavy plinth, one in a light plinth (have not listend too much to that one yet). One thing I found, that you may not have to deal with given the "new" nature of your table, is that the lead out wiring insulation on both motors has broken down badly over the years. By the way, the heavy plinth seems to work well, though you can hear the table from a couple feet away. I've used both an RB250 and a Audio Technica 1005 II on the table with good results. I'd suggest a big hole for the tonearm and then making mounting plates to fit over that to accomodate different arms. Oh, and I found that a "Herbie" mat sure beats the standard ROK heavy rubber mat. Best of luck!
