If it was me I'd go with the Burris Signature Zee rings with the inserts. Do a search on google, or other forums and you will find how highly people think of them.
IMO they are the best I've used in that price range. I like them a lot better than the Leupold rings I've used. A local shop has also started really pushing them, as their gunsmith loves them. I just don't think you can beat them for the price. Since they have the inserts, you don't need to lap them, and you won't get any ring marks on your scope. Plus, if you need to shim them, which you usually don't but just in case you do, you can get offset inserts.
