I've got a pair of Nikon 10X42 Monarch ATBs I love. They're bright, sharp, easy to use, and super to work with. IMO, they're a great buy in the $300-350 range. I've used less, but nothing that pops into a sharp edge-edge picture the way the Nikons do. I'm sure there are others higher up the scale that would be better, but I haven't reached that point of addiction yet.
