Dennis, you've gone and got my dander up with your sweeping statement that newer binoculars "are way ahead of older models in brightness and contrast due to improvements in coatings". "Even the less expensive newer binoculars are brighter than the older Alphas like the HG". What tosh!
The Nikon HG(LX) series is famous for having 'state of the art' lens coatings, with exemplary contrast and brightness, as well as sharpness, so much so that the new EDG, superb though it is, is only a slight improvement over the older Premier line. Other HG attributes are focus smoothness (seldom equalled and never surpassed, the envy of the entire industry) and build quality (as good as any, better than most). To buy such integrity for around £310 ($500) as I have done, in used but nice condition, is patently far better value than paying the same or more for some new, non-Japanese, relatively unknown upstart still wet behind the ears with only advertising hyperbole to extol its alleged virtues. We KNOW Nikon HGs and SEs are good, with legendary optics and build quality. By way of example, I had a Hawke Frontier 8x43ED for a while, which cost £220 at the time I bought it new. It was good, very good, but not a Nikon, so I knew it would eventually be replaced by a Nikon, after which I'd have peace of mind...
It reminds me of a story I read in 'Car' magazine some years ago, when Aston Martin were trying to enter the 'gentleman's carriage' market (then dominated by Rolls-Royce and Bentley) with the Bill Towns' designed Lagonda, a futuristic wedge-shaped, all-electronic/digital V8 grand tourer, dearer than a standard Bentley T2 of the time (1970s). At the Motor Show a R-R agent strolled over to the Aston Martin stand, paused, kicked the tyres of the Lagonda, and enquired laconically "Are these any good yet?". I rest my case...
