I've been using one of the Case-Gard pistol rests since last winter. It has done a decent job, well worth the price. I fit a small pad of lambswool to the Rubber V to keep the rubber from splitting. A scrap of an old bath towel should do the same thing. Mine started to get a split in the rubber a few months ago.
