Hi Sam. The VibraPods looked good until I read this;
VIBRAPOD Isolators may leave rings on woods, acrylics, and painted surfaces. They may also dissolve the paint, especially if it is lacquer. To protect these surfaces and your equipment please use BAR COASTERS or PLAYING CARDS between the VIBRAPOD Isolators and these surfaces. AOL Discs work well too.
Squash balls it is then!
Yes, this could be an issue. I have mine resting on glass shelves and that doesn't leave any marks.
