Motor Vibration and Mics

Ok, after playing around for about 3 weeks trying to reduce the amount of vibration noise being picked up my my shotgun mounted to the camera, So far I've come up with:

I bought a telephoto support that I have my DVC30 mounted to and holding up the letus and lens. I choose this due to money (I bought it for $60). Now I have a DVC30 with the XLR adapter and mic mount. I also have a cold shoe rubber band mount for my NTG-2. I get a fair amount of vibration noise in the mic with either mic mount. I've place a rubber pad under the letus that rests on the tele mount. I've also put a bit of rubber where the camera mounts to the support. This has helped a lot even though the mic is mounted on the camera. It just seems to absorb the vibration. The XLR adapter has some rubber bushings and of coarse the rubber bands that holds the mic. Still, I get vibration noise. In a medium noisy environment, it's ok. Just very quite places I can hear it. (yes I have the high pass filter engaged on the mic).

Other than mounting the mic off the camera, has anyone found a fix? Is there a way to either dampen or float the vibrating GG from the rest of the adapter? Maybe another kind of support for the mic?

In keeping with the higher production values people aspire to when buying or building 35mm image relay devices, the next step is ideally to find and use a better mike, on a lead long enough to keep it well away from the camera, its mechanical noises and the noises of the operator moving things about in the lens area -- and in my case, the whistling of congested nostrils and the resonances of the odd long nose hair.

(the darth-vader sounds on the savefile clip are me, not the actors because I was using the on-camera mike and stooping forward over the camera as I held it at waist height.)
