if you take say 3x9x40 scopes,there is a big differents between the 40.00 scopes 125.00 scopes after that in most brands you won't see much differents until you get up to 300.00 range.

i find that for normal light the 125-200.00 scopes will do in most deer hunting .i'm just to hard on those high end scopes to carry one around much.
