If you're thinking of spending close to $500 on glass, there's no reason to even consider a Tasco. You could get a Leupold VX3, a Zeiss Conquest, or a Nikon Monarch for $500. For considerably less, you could go Nikon Buckmasters, Leupold VX2, Bushnell Elite. The last ones are in the $300-$400 range. I would rather shoot a budget rifle with good optics that a custom rifle with a piece of crap on top of it. No rifle is better than the scope.
