I've had a whole series of Binoculars over the years finally resulting in a set of 10x42 Leica Ultravids which frankly are better than I need and have the glassing ability to use. I also have a set of 6.5x32 Minox IF,s my son uses a set of Pentax HP11 8x42, I had a set of Pentax Sp's prior to the Leicas, very good.
If I was spending $400 today I would look at Pentax first then Minox. Leupold is overpriced, not that great, the big three Leica, Swarovski and Zeiss are all great but well over $1,000 , don't get mini's, Nikon makes a whole range from cheap to fantastic, but they don't feel great in my hands.
