I saw them on sale once, more like 350 - 400. Still quite high, no argument here.
I wish more people buy them and the price goes down
Other than this, I've used (and still use) 2 pairs of Zeal goggles (PPX, SPPX) and I think they are great, better than anything else (though some light conditions can still be challenging). They were recently bought by Maui Jim, that's how good they are!
