whats the difference between a nice scope and a realy nice scope? im not talking about the diferance between a $30 wally world special and a $500 scope. im talking the diferance between a nice $150-$200 Vs. a $450-$500 scope. iv looked at pantex game seekers ( $180), and Nikon Pro staffs ( $200 ish). and before i drop that kinda cash i want to make shure that there is no way im going to want to turn around and buy a $450 one cause of a cool feture that it would have.
