Take a look at the F-2 Titanium Heavyweight Counterweight from Audiogon member, Gregory_Kerry. I have been continually astonished how it upgraded my Rega RB-300, and resulting vinyl listening pleasure. Similarly, I found a smaller, but meaningful upgrade when I replaced my Ringmat with the Non-felt mat, although the Herbie's mat is beloved by some other members. I don't know if choosing one of these mats would make changing the entire platter less of a priority.
