One more thing to keep in mind about binoculars.  Coatings are very very
important.  A pair of 7 or 8x30 binocs that are of high quality will
transmit a good deal more light than a medium grade 7 or 8x50.  I have,
as I mentioned last night a pair of Zeiss 8x30's and a pair of Stiener
8x30's' which will let in as much light as an older pair of Leica 7x50s
that I own that were made in the fifties.  The older Leica's have
incredible optics and a very large exit pupil but the coatings just
aren't what they are now.  When you consider buying a pair of binoculars
keep in mind that just because a manufacturer says the lenses are coated
doesn't mean that they all are coated.  The high-end binocs have
coatings on all surfaces of all the lenses.  You'd be amazed at how well
you can see in low light with the Zeiss 8x30's.  Even my Leica 8x20's
will let in more light than many of the larger mid-range binoculars
though the small exit pupil make them a bit impractical for using from a
moving platform.  The other great advantage of good quality optics is
that you can look through them for hours on end without eye fatigue. 
The next time you check out a pair of binoculars compare them to a
really good pair.  In addition to high light transmission you will also
see a clear image all of the way out to the periphery of the lens. 
Again it makes a big difference in the long run.
I agree with Steve Holtzman.  Buy the best you can afford.  A good pair
will last you the rest of your life.
