I use a Minus K and love it under my Brinkmann Oasis. I used to have a second one under a Clearaudio. You have to weight them to their limit, though, to get best results, and balancing your TT on them can be a little challenging. I use heavy brass discs to distribute the weight. Also, they seem to work better if you put a shelf or platform on top of the top plate--I use a Adona multi-element shelf.
