Spot on Alick, they only really come into there own at the higher magnifications, where as Alick said you have no hope of holding them steady by hand.
They do come with quite a hefty price tag, about £500-£1500. They are the future of optics, along with auto focus. But then the more electronics you introduce the more possible pitfalls. If you are depending on bino's for your life then simple and reliable is the best option.
If i was spending that kind of money I would go for better optics with less magnification, and steer clear of the electronic gimmicks.(IMO)
Now another interesting pair of Bino's especially for you buckshot, is a range finder pair made by Bushnell. These give you a range to target for shooting which I feel could be useful. Again though you compromise on the optics, which are very good but not upto Steiner or Swarovski, Leica & Zeiss.
Cheers
