Originally posted by Blacky: I have no idea about the cost, yet, but it can be shot off the shelf. It's pretty much like all the other risers with a flat shelf. You can use felt pads from Wal-Mart and put one on the shelf in conjunction with a low berger button. Or you can use two felt pads.The picture shows, how to fix the pads. I found that pic at the Pirate's forum.Blacky
