Personally, I really like my Smith Slider SL2's. The very nice feature of these sunglasses are the quick change lenses. The frames, with 3 sets of lenses (brown, orange, yeller) is $100. A set of polarized lenses is $50. I own both the brown and black/grey polarized lenses for different lighting conditions.

Again, like any pair of glasses, be sure to try on a pair before purchasing them. The only "good" glasses are ones that fit my face.

Gregg's Greenlake Cycle in Seattle carries the Smith SL2 glasses.
