As Joe mentioned, Nightforce is excellent bang for buck. They are not all that cheap but quality and performance is generally very high for what you pay. I was much more impressed with my Nightforce than my Leopold. Originally I was just a phone call away from buying a Schmidt Bender. If you ever get one of these in your hands, its the holy grail of sniper optics, or any optics for that matter. I have put my eye to every high priced name brand scope out there and the Schmidt Bender is incredible, however, at twice the price of the Nightforce, as a nice surprize, the Nightforce was close. Not as good, there was a difference, but not twice the price difference.
US Optics also make a very high quality piece of glass, but they are in the same boat as the Schmidt Bender. Lots of $$$.
If your looking for a great product for the cash, go take a look at the Nightforce line. As a side note, their customer service is great as well.
Good luck.
