I was going to recommend the Leupold Mark 4 (I have 6 or 7) until I looked at the unit 257tony recommended. If I get a new scope the Vx6 will definitely get serious consideration. I have always had good luck with Leupold products, although the clicks on some of my Mark 4's are a little soft and "spongy". I have one Huskemaw (decent glass, crisp "clicks") but don't really like the 1/3 moa adjustments. I have a Swarovski X5 that is absolutely incredible in virtually every way, and lighter than the Nightforce and Schmidt and Bender products, but it is over your price point.
The Nightforce products are to heavy for me and I have never been impressed with any of the Vortex products, but to be fair haven't really looked at them in the last year or so.
I like 257tony's recommendation, but have no personal experience with that specific scope........so not sure if the "spongy" click problem I have with the Mark 4's is also a characteristic in that scope.
