I've been using 2x12 cut into 12 inch squares. The nice thing about them is that I can stack them if needed to help compensate for unlevel ground preventing unnecessary extension of one or more levelers. Been eyeing the snappads, but have not decided to pull the trigger yet. Might wait a bit to see if the prices come down a bit. Seem a little pricey for pads made of recycled tires. They are definitely appealing though.
