One would think
the Vixens being Nitrogen-purged & "updated" technology, per se, would provide better views than the Megaviews that came out a decade ago but I'm not so sure hence the research.
Not sure how you define "updated" technology.
I have not seen any updates to the Vixen ARC series over the years.
They have been only multi-coated for as long as I can remember,
whereas the Orion MEGAView 30x80 was Fully Multicoated at the time of its being discontinued.
I have never exposed my Orion 30x80 to any conditions where the Nirtogen-purging would have made any difference.
My Orion MEGAView is built like a tank. The Vixen 30x80 ARC was less impressive, in my hands, as far as build.
I would not hesitate to buy a used Orion 30x80 if it appears to be in very good condition. The majority of my binoculars were purchased used.
The binocular case pictured in the eBay photo is identical to the one I have.
As far as collimation is concerned, any binocular can be knocked out of alignment due to rough handling during shipping, especially ground shipping.
Nowadays I always insist upon USPS Priority Mail to avoid binocular torture.
