I have had both the Leica 1200 and the Swarovski 1500. The Leica was a little handier, but the Swaro ranged a bit further and the 30MM objective was brighter than the 25mm Leica.
Both are awsome. I have also had lesser rangefinders, and I gave them to my JR PETA members to play army with and range to their skateboard with. For me, that is all they were good for!!!
