Under speakers Vibrapod or Gaïa


Does anyone compare Gaïa and Vibrapod under speaker ?  With Vibrapod,  for the $, I have great result under my speakers, but, does it worth the extra $$$ interchanging with Gaïa ?

I suspect the cable company will refund your purchase if you don't think the isoacoustics are worth money. Probably worth a try, I know I really like mine. 
The real choice is between the GAIA and the Townshend Audio Seismic Pod products.
