I believe Monarch > Prostaff and if you're patient I don't see why you can't snag some 8x42s for $150-200. I had the old ATBs but IDK all the differences between the new '3, 5, & 7' models. I think you have to step up into the 5 or 7 to get the dielectrically coated internal prisms, but all (including the old Monarchs) should have fully multicoated optics, which are the bare minimum for quality standard for hunting optics.
