I bought the Expressimo Audio Heavy Counterweight for my Rega RB-900 about two years ago, and posted a "rave" review for it, saying that the improvement it made to my turntable/tonearm combo was NOT subtle, and was the most significant "tweak" to my analog system I'd ever experienced. Since that post, the Expressimo Counterweight has been updated. I do not have any experience with any other counterweights, but on the basis on my experience with the Expressimo unit, I enthusiastically endorse it!
