Yes, leupold makes great glass, and more importantly they stand behind their product. But there are other great companies out there.
If you can afford it, Zeiss, Kahles, Hendsolt, and some other european companies are EXCELLENT.
Nikon and Burris make very very good mid range product
B&L (Bushnell) 3200 series is a very good low-mid range brand. I've also heard sightron makes good stuff in the same range, and I am working to get one to evaluate and find out for my self.
There are some other wildcards out there also that at least warrant a look, Nightforce, ATN, US Optics, etc. But, if you do want something that you know what your getting, it is hard to beat leupold.
