$100+ is a lot for a pair of sunglasses, but it was well worth the investment.  I would most often use cheap $10 pairs of sunglasses that would break after a couple months and broke my most recent pair.  I decided to take the chance in the investment and was glad I went with Oakley.

The sunglasses (Polished Black/Black Iridium) are sturdy, comfortable, and work very nicely.  They are a comfortable mix of shade without being too tinted.  There's a little rubber on the inside that sits well on my head.  I have forgotten that I am wearing them at times while driving.  Recommended.
