Try doing a search over at opticstalk.com. There should be quite a few opinions on both.

I hate it when I ask a question about product "A" versus "B" and someone goes and recommends product "C", but I am going to do it anyway, only because there is limited time to act. Consider looking at a Vortex Viper 2-7x32. For not much longer you can pick up one of these for around $170. Apparently Vortex is discontinuing the 2-7 Viper (but not the Viper line). The glass and build of the Viper compares favorably to the Nikon Monarch and Bushnell 4200 lines, meaning a significant step up from what you are considering, and for less money.

Not affiliated or anything. In fact, I picked up a 2-7 just before they slashed the prices. Bummed about not waiting a few months, but am very happy with the scope.
