Buy binos that are comfortable in your hands as well as hanging around your neck. Hunting binos need to have a WIDE field of view. Stay away from mini or compact models- too narrow field of view and tough to hold steady. As in rifle scopes, buy the best optics you can afford. They will last a lifetime if you take care of them. Always ask to take the binos outdoors for a test view. Indoor lighting does terrible things to decent optics.
Take a look at Swift. They are held in high regard in birding circles- and some birders are neurotic about their optics. I've had the Swift Audobon 8.5 x 44s for years. A bit large but they have excellent brightness, great field of view and clarity, rivaling Swarovski. They have a new version that is now waterproof, these will be my next binos. Take a look at:

The Pentax 8.5 x 42's are very good also. Nikon makes a good product. Yes Swarovski, Leica and Zeiss are expensive, for good reason. But with a little research you will find a nice set of binos for a decent price. If you need more info take a look at:
