Mike,
Brunton makes some good optics. As a birdwatcher though, I've looked through many binocs, and the improvement in quality increases with the tag. Swarovski, Zeiss, Leica, Leupold, etc. are all super-expensive binocs, but they are extremely efficent at gathering light in low-light conditions. I've found it helpful to identifying ducks coming in right at daybreak, or right when the sun is going down. The crisp image is hard to beat, and they are waterproof- I've used mine underwater!
The downside is they are expensive, and there's many comparable brands that also do the same job- clearly magnifying whatever you're looking at. I'd say go with Brunton unless you stake a gold claim anytime soon... =)
Hope this helps,
