I personally own a Leupold Vari-X II and VX II. I have just puchased 2 Burris Fullfied II with Ballistic-plex recticles, after shooting my fathers H&R Ultra Slug with one. Can't say enough about the Burris, I think the optics are better than my Leupolds. Plus its a single tube scope, you don't get that with Leupold until you go to VX III and that a huge jump in price. For the price you can't beat a Burris....
My friend has Nikon monarchs and the Nikon Omega and I am here to say they are nice scopes, but I'm sticking to the made in the U.S.A. brands.

P.S. I think Natchez shooter supply, Midway USA,Gander Mountain, and Cabelas are currently running dealson Burris Fullfield II's 3x9x40's. For$189-199 you get the scope and your choice of binoculars or spotting scope.
