They do weigh a little more, but not so much to be an issue. I purchased the 8x42 model thru Eagle Optics while they had a great deal going. But even at the regular price, you will be hard-pressed to find a pair as good as these at the same price.
If $2500 Zeiss or Swarvoskis are out of your price range, then do yourself a favor and get the Vanguard Endeavor ED 8x42 Binocular. You will not be disappointed. As I said, I purchased thru Eagle Optics, and you simply will not find friendlier, more knowledgeable customer service.
