Isolation Stand/Base For PS 300?

A while ago, I recall a classified add from a dealer for an isolation stand/base for the PS 300. Can't find it now. Does anyone know who was selling these? Thanks!
Hi, it's Rick Brkich at Signature Sound, Liverpool NY, 315-622-4137, or email I bought one about a month ago for $79 plus $15 shipping and it really looks great! Plus it gets my P300 off the piece of bookshelf I had lying on the floor and up on a rigid custom stand w/giant spikes. It's really a great product, highly recommended.
Srah - Thank you! I'll contact them. Alex
Any difference in sound after you use the isolation for PS 300?
