You could go with a Burris Fullfield II and use Burris Signature double dovetail and Signature inserts. I've got these on a .30-06 Remington ADL. That scope is outstanding and an excellent value. I've got the Ballistiplex reticle, but I don't use it. You can get a scope w/o that reticle.
The Signature rings w/ inserts are self-centering, so mounting a scope is easy and flawless. You can adjust the scope in the rings, if needed, before touching the adjustments on the scope. By doing this, you are truly looking down the center of the scope, more so than if you make large adjustments with standard rings (no inserts).
You should be able to buy all of this for <$250. As mentioned above, the Nikon Monarch would be another excellent choice.
Good luck.
