Building your own high end turntable stand?

I have been looking for a reasonably priced, heavy, sturdy, rock solid turntable support and apparently those words don't "fit" in my budget....so...I thought I would try to build my own. Was thinking about a thick marble top??? Does anyone know where one could find plans or at least good guide lines to use? I want this to just support my VPI and be waist high....no other electronics to generate vibration or noise....any ideas????? Has anyone built their own or has a good idea as to what would work and is willing to share their imagination??? I hope to hear back from a few members...I know its not going to proform as well as one built professionally but I can't afford 2 or 3 thousand dollars on a stand.

thanks, dean
