Swarovski! Mine has never failed me. I started with a nikon prostaff, then upgraded to the monarch 1200 but both were useless in the "elements". My buddy has a leica and likes it but he doesn't like it when I have to range for him because of weather. Also my swaro ranges out to 1200-1300 yards pretty consistently. One day even 1600+. Just don't go cheap you will end up upgrading in the future.
