Well, you'll either love it or you'll hate it, so try to hold one if you can. I bought a Savage that came with one and I really enjoy it. It's excellent for shooting prone (99% of my shooting) and offhand shots I find I get a little bit more stability. It isn't awesome for the bench though because of the angle you tend to hold it at I wiggle quite a bit when I'm just trying to shoot off the bipod vs. a conventional stock. Could be just me though. Another thing to think about is the winter shooting, it's awesome for summer obviously because you aren't wearing gloves, but in the winter with big gloves I imagine it would get a little bit awkward. Chances are you'd be taking them off to feel the trigger anyways though.
Hope this helps.
