I do believe there is quality glass available at the $500 range now that you had to pay more to get 10yrs ago.
I don't believe that spending less today is a penalty.
I would still buy Swarovski if I had the budget to do it, but high-end Nikon, Zen-Ray, Vortex, Minox, Pentax, Meopta....they're all going to be great.
Technology advances, prices really don't inflate in some categories.
Buy what you like.
