Recently Ibought a Caldwell "The Rock Jr." and I love it. I paid $40 I think it was at Sportman's Warehouse for it. I don't shoot a lot so I wasn't looking for something that would cost me and arm and a leg. For a back rest I took a tube sock and filled it full of rice and tied it off. The reason I like the rest over the bags is that it allows me to adjust up and down easily. It's very solid. Growin' up we used to just shoot off the hood of the truck on pillows... My-my how times have changed.
