I heard good things about Vortex products, but have never purchased any. I own several makes, two of which are Zeiss conquest products.
Not only am I unable to file a single complaint about the Zeiss scopes I own, I've never read anything negative about a Zeiss scope. You could say, compared to other makes, Zeiss pricing for new scopes may get a little high once you move up past the 3x9x40. If you shop around you can find a deal. The bottom line, it's still a Zeiss and that selection is hard to criticize.
