I'll second Mojo and most of the others here too! Get the best you can get!
I used to think that it was foolish to spend the extra money for a better scope. But I had 2 cheapies fail me, one of them on a on a hunt!
My suggestions would be Burris, Nikon Monarch, Bushnell 3200 or 4200 or at least a VX-II Luepy. A Zeiss Conquest would be about as high as I'd go!
I believe you really get what you pay for in scopes but, I also believe that you reach a point of "diminishing returns" once you get into the Luepy VX-III price range! Good luck!
