I have had two pairs of Von Zipper aviators at $80 a piece:
These were ok, fit a little small on my head and were very fragile. I bent both frames that I had and I am not very rough with my glasses. The lenses were awesome though.
I now have this pair, $90:
I like the way these fit and the size of the lenses a lot more, but they mess up my depth perception so backing up in a car you might want to take them off. Other than that, they are my favorite pair of sunglasses I have ever worn.
