You'd be hard pressed to go wrong with a Leupold, top quality optics, Nikon is a close runner-up. Unless you want to go ape crazy and spend$$$$$ on a Zeiss or swarovski(sp?) If your looking for a good optic for a very reasonable price look at the simmons Aetec line. I have owned a few and not one complaint from me. Some of my rigs have Leupolds, others have Aetecs, I favor the Leupolds for low light performance and clarity, but they're also double the price. Depends on what your going to be doing and how much you want to spend. Good luck!
