There are plenty on the market. Stick with the known brand names like Nikon, Minolta, Tasco, Bushnell etc or if you can afford it look at the Steiners, Zeiss etc.
For compactness get the roof prism (straight barrel tubes) for slightly lighter in weight, get the porro prism design (zig-zag lens tubes).
For general use a 7X21 or 8X22 should suffice. Anything higher powered will irritate you as handshake is magnified with these small light binocs. Also higher powers can make it harder to find your target, especially in wooded or featureless terrain (snow, desert) as you can wind up waving the binocs all over the place trying to find your target (esp true with moving birds). Most times you don't want to see target detail (unless you're a bird watcher) but you want to identify something you can't quite make out with the naked eye.
But most important - don't buy via mail order. You must check out the binocs yourself, in the store before you buy. I went through a pile of Minoltas before choosing two, one for myself and one for my wife. Focus them for your eyes, then look at objects close (3 - 10 metres) then further out to the far distance. You should have a clear. round picture with no black 'clipping'. The picture should be clear, look 'normal' (no double picture) and you should not feel like your eyes are becoming strained after a minute or two of peering through them. To check for chipped lenses look through the lenses in reverse - any chips will be seen as black nicks on the edges. You'll be amazed at the difference in quality (lens barrel misalignment mainly) on the lower priced binocs.
If you wear spectacles then get a pair on which the rubber eyecups fold down for spectacle use.
Good luck and have fun with them!
