Turntable isolation platform Recommendations?

You obviously have had the experience. We tolerate the crap weather we get the rest of the year just for Autumn, the finest weather with technicolor. I live in Southern NH. My brother has a condo at Saddle Back mountain in Main. I drive a 911 C4S year round. Maine only has enough money to afford State Troupers on the major highways. There are thousands of miles of two lane back roads ( B roads) that are unprotected except for the local constabulary in the small towns. You just have to slow down when the speed limit drops before these towns. Other than that it is....open season:-) Catching air, lurid slides, big fun. Very little traffic. I use to autocross but it was taking up too much time and money. I stopped when the kids came along. 

@whart , forgot to put your label on the post above.

I'd love to go for a drive. 

I use an HRS base under my Brinkman Balance - works really well, highly recommended 

I know probably very few people want to hear this but active vibration cancellation platforms like Halcyonics are a revelation to vinyl playback.  
It works exactly like the scanning electron microscope before and after images shown to illustrate how they work.  Turning the platform on seems to “focus” the sound just like it does for images.  Even off, I believe the platforms give some some benefit in very low frequencies. 
I have a bunch of active vibration platforms which I have to get into service.  They will come in handy once they start building the second Ave subway in my area of NYC, and vibration will be pretty bad as I’m probably 150 ft away from the dig.
