...and to make sure all your cash is spent, personally I put far more emphasis on the quality and low light view of the binocular over the riflescope for results.
fwiw...
IMHO the two go hand in hand. You need to be able to safely and properly pick out the "right" target when looking through the rifle's scope. This is important in very low light when transitioning from binoculars to scope when there are more than one animals in close proximity to each other.
