I was curious about bipods a little while back. I bought a Cadwell which is a cheaper option, it works great. I am really happy I bought it, I use it at the range, use it to plink squirrels with my .22, and it's a lot of fun shooting prone. Going to try my hand at coyote hunting this weekend, bringing the bipod along.
Just make sure you you get one that swivels so you can set it up on unlevel ground.
