The Kahles brand of binoculars, in my opinion, are a bit overpriced for the optical quality that they deliver. Cabelas sells them from $700 on up, depending on configuration. I would probably opt for a Pentax DCF-SP before going the Kahles route as I feel they offer better optical quality for slightly less price.
I concur with that they are overpriced...I think you can get away with 30's in a lot of cases if they are excellent glass plus they don't put a crick in your neck. I have dealt a lot with

www.eurooptics.com and they can be very helpful in making a decision.
