turntable isolation feet


Which isolation feet work better? Rubber, metal cone, ...?
Does it depend upon turntable styles -- belt drive, direct drive, idler wheel?

I've found many isolation feet made of rubber or metal under $20 in eBay. What would be your best pick for turntable isolation feet for under $50?

Thanks in advance.

I'll give a try to viropods. I had used a bike tire once. With an inch thick wood chopping board. I will also try it and see if there's any difference.

Thx
When I upgraded my butcher block from a 1-1/2" "hardwood" board to the 3-1/2" thick norther maple board I use today (with the Vibrapods and cones), I got a noticeable improvement that even my wife could hear right away.
Just switched to Edensound's TerraCones for my Scoutmaster. This was a significant upgrade. Immediately I noticed an increase in clarity. The soundstage became more three dimensional and the presentation more forward. I also made the switch with my speaker's spikes to his TerraCones with similiar results. I can't believe this guy's stuff.
I use Boston Audio's Tune Block with upgraded Tungsten Carbide (original ones were steel) ball bearings under my Kuzma Stabi Reference TT.
