Some of the 'so-called' bargains are still ridiculously overpriced.
The best advice is to avoid 'new' glass. And the very best bargains are found at local forums.
In 2017 I sourced very clean 8x32 swarovisions for $875 and equally stellar Zeiss Victory 10X42's for $675. Both came with cases...extras....and both just sitting there with "best offer"........Together that is the discount price for just the Swarovskis.
If one isn't stuck on "new" the glass is out there. With the stellar warranty service of the alphas why buy new unless one likes to spend money?
The million dollar question...
