Opinions: Neuance Shelf for Linn Sondek Lp12 TT

Let me start off by saying that I am using a wall mount system with steel points under the shelf. The shelf is nothing special, just laminated MDF. Problem is, I am getting some vibration in the shelf and I would imagine the table. Linn's Ivor Tiefenbrun recommends a rigged and light weight shelf. A Neuance shelf appears to fit the bill, rigged, light weight, inexpensive, and has some good review. Other than that I know little about Neuance by Greater Ranges. What do you think?
And does anyone know what is up with Neuance? I have written them twice, days ago and still no response...
