I used to really like the Leupold VX-1, I have 4 of em, but after getting a few Nikons, 4 Prostaffs, 3 Buckmasters, a Monarch and 2 Omegas, I'm thoroughly convinced the Nikon is a better buy and just as good if not better in quality and light transmission, the Monarchs are 95%, and the Buckmasters and Omegas are 92%, the Prostaffs 90%.
