I have never paid more for the scope than the gun,and I don't believe that it is necessary.However,I do prefer higher quality scopes,so that I can get the same brightness,with a smaller diameter objective,which allows me to mount the scope lower.
As far as what people spend on guns and optics,it comes down to their priorities.Some people willingly spend several thousands of dollars every year,smoking, drinking or gambling,yet those same people can't understand paying $1000 for a gun ,or $500 for a scope.I can't understand how someone can spend thousands of dollars per year smoking,or drinking ,or feeding money into a VLT.
However,what I really find ironic,is when those same people that smoke,drink and gamble away their money,attempt to ridicule the people that choose to spend their money on higher end rifles and scopes.Jealousy is ugly,but when you have the money,but simply choose to spend it elsewhere,it makes even less sense.
