I have some Leica Geovids 10x42. Great glass and a great rangefinder. I love them. They don't have a 12x50 model but do have a 15x56 if you wanted to go for more magnification over the 10s.
I bought the Leicas over the Swaros because the Swaros won't range under 33 which I didn't like for bowhunting.
