I have used 3 different footers under my sand box and can tell no difference between them. My gut tells me that the sand is absorbing a great deal of the vibrations and therefore the footers are not that important. Note that I have never set the sand box directly on the shelf so I don't know what effect that would have.
IME there is a noticeable difference in the platform material used atop the sand upon which the TT sits. I am experimenting now with the sand box vs maple platform. I'm hoping to do a review and comparison of the 2 soon.
