IIRC Prothanes are around $80. Energy Suspension is much cheaper around $40..
Filling them is just removing the mount and using any kind of adhesive sealant to literally fill in the spaces in the mount. If you have seen an engine mount or roll stopper they are a piece of rubber with cut outs on top and bottom so that the center section can move up and down, thus dampening the vibration. Fill in that gap, the engine cant flex much anymore and you vibrate more but bit more power to the wheels..
Depending what you fill with will determine your overall ride quality. RRE says to use windshield polyurethane sealant, the stuff they glue ur window down with. This is on the vfaq under suspension:
