Shato,
Nikon makes a good one,and the Wind Rivers by Leupold are good also.These all should be under 500.00 bucks,stay away from the Burris Landmarks pure crap.I had 2 of them.The first one I bought was very hazey,so I sent it back and Burris replaced it,and it was not much better so i sold it and bought the Nikon.
