The best bang for the buck in my opinion is the "refurbished" Nikon 10x42 or 8x42 Venturer/LX's that can be had from
www.Ewins.com for right around $450.00 shipped. I've made two purchases from Ewins.com and both were flawless. Pretty hard to beat their price for world-class glass.
The refurbs are backed by a limited 90 day warranty, afterwhich they're covered by Nikon's "no fault" lifetime warranty, which allows you to send them back to Nikon for repair or replacement (their option) should the need ever arise for $10.00 plus the cost of return shipping, which is usually $7.50 in the lower 48 States. There's no questions asked and it doesn't matter if the damage was your fault. It's that simple.
I've owned Zeiss, Leica, Pentax SP's, Bushnell Legend's, and the Nikon Venturer's. And while the SP's and Legend's are pretty good glass for the money, IMHO, they're nowhere near as good as the others. The one drawback to the Nikon Venturer/LX's is their weight, but it's not unbearable with a good strap or harness system.
Another great deal is the Zeiss 10x40 ClassiC's from Cabelas for $699.99. They're crystal clear, lightweight, and dang near bulletproof. Just a few years ago they retailed at almost $1100.00, so $699.99 is a bargain.

I used to use cheap and mediocre binoculars until I made the mistake of looking through a buddies 10x42 Swarovski SLC's. Needless to say, I was hooked. Having looked back, if I could do things all over again, I'd have forgone buying a couple of rifles years ago and dropped the money on top quality binoculars instead.
I read somewhere once where a guy said, "No one ever looks through one of the top brands (Leica, Zeiss, Swarovski, and Nikon Venturer/LX's) and says, what's all the fuss about?" I couldn't agree more.
Good luck.
