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..

I have my Gold Note Mediterraneo table spikes(3)sitting on 3 SSC Netpoint 300’s, which sit on a 2" thick wooden butchers block, which is seated on 5 Nobsound springs on a Salamander A6 walnut stand for they’re base. My form of "table isolation" cost me all of $250 to do, plus the little L shaped level sitting on the butcher block.
All you need is butcher block acoustics walnut or Maple slab. Place it on top of several vibrapods spaced symmetrically. Very economical solution. Better yet, place the slab on top of both vibrapods and their companion cones....still a helluva lot cheaper than HRS or the like. I think they call it the vibrapod sandwich. Ultimately, I would place the turntable on a made for turntable wall shelf mounted preferably to a dry wall dressed concrete wall. Then use the above vibrapods and butcher block acoustics slab. 
I have the HRS M3X2-1719 isolation base under my Rega P6. Yes, the base cost more than the table but I plan to upgrade TT moving forward. My TT is mounted on a foundation wall but one of my subwoofers is very close to the TT. I have been really pleased with the performance of the HRS - I’ve only had one instance where I heard feedback to the table but that was before I dialed in the setup. I have not had any issues in the past 2 years whatsoever and I tend to play loud. 
I feel kind of odd providing an on- topic post give the history of this string.

Hi.Check with Music Direct and/or The Cable Company for Pneuance Audio Pneupod Pneumatic Isolation Device (footers) www.pneuance.com. You can try them with 30 day return. There are adapters for the Innovation Series tables which are not needed for your flat bottomed table. The chief designer at Clearaudio has a set of Pneupods sent for audition for the Innovation and loves them. You may not need an additional platform, though they can work with them. They add the isolation and suspension many modern tables, with a few exceptions, need but are lacking.
