As a follow-up to my previous post, I checked the price of Symposium bases, and they range in price from $600 to $2,000. The SRA VR 3.0, which is custom made for the particular component it's supporting, runs $475 to $675. That's a considerable gap in price, one that I don't think is justified by the performance of the two products. In my experience, SRA products are without peer--even including the Symposium--and the VR bases are the company's biggest bang for the buck. And for $2,000, you can get the Ohio Class XL+ bases, which blow away anything I've heard.
