I use SRA platforms under most of my components and my experiences are overwhelmingly positive. I've tried quite a variety of platforms and footers and have found that while most of them clearly affect the sound in some way, it's usually ambiguous whether the change is a net improvement or not. With SRA platforms I've nearly always found the improvement to be unmistakable.
Besides the VR platforms the SRA web site lists a cheaper Tremor/Less range priced at about $300-$350 per piece. However it's not clear whether it's currently available. They went out of production a number of years ago, but then a couple of years ago a new Tremor/Less line with different cosmetics and internals turned up in a Stereo Times review:

Naun.
