I had a pair and I didn't really care for them. One eyecup broke with minimal use, and I felt eye position was critical to a good picture. The 15x swaros are soooo much better.
I have heard that the 13x minox are a great bino. Check with doug at cameraland.
I've got 'em and I love 'em. They are big and heavy, but once you get them set up solid on your tripod, they are extremely effective. I would imagine the Swaro's are probably better, but a big price difference.
