I'm in the process of building a rifle and would like something in the 6.5-20x50 range. I like the 30mm tube on the Vari X-III. I have also heard some good things about the Zeiss. I've also seen alot of Leupolds for sale on different forums lately. I'd like to hear your likes and dislikes on these two scopes. Also where is a good place to purchase both brands, with price and service in mind. Thanks for any info.........
