Turntable isolation platform Recommendations?


I currently have a Critical Mass isolation platform on loan. Does anyone have any other suggestions I might look at?  Possibly considering the HRS 

any feedback would be greatly appreciated..

Turn Table rack by 
“MapleShade” uses three 4” solid Maple shelves. Turntable sits on
top at just the right height for playing vinyl.
Vibration is greatly cut down by 
its design...four solid thick metal rods are secured and screwed in 
Tightly on the bottom and top of each shelve. Very attractive as well.
I have a Garrard 301 mounted in an Acustand Solid Plinth2, so I don't use a separate platform. Just three IsoAcoustics Orea Indigo feet is all I need. My 'table sits on a heavy mid-century modern buffet. I can strike the buffet  with a mallet while an LP is playing with the plinth sitting on the IsoAcoustics feet with nary a skip or a jump. Strike the plinth itself the same way and all hell breaks loose. I used Sorbothane  footers before the IsoAcoustics Orea feet and they were about half as effective.
