Thanks all, looks like most think that they are worth the cash (polarized if not the Oakley brand).
I did see the benefit this morning actually, its a rainy morning here and rather dark. I have black polarized lenses on the Crosshairs and I tried the glasses while driving just to see the impact - they improved visibility quite a lot by cutting light glare the rain was reflecting. So even with the dimming effect of the lenses (I think they are 14%), I could see better. I just worry something will happen to them, I had Oakley Whiskers (non-polarized) I had got for $80 and I had them in my pocket - bent over to pick something up one day and they pretty much disintegrated ;-(.
Somehow I find that hard to believe. I own 3 pairs of whiskers myself... 2 of them are the tianium frames that I use every now and then...the other one is a normal metal frame with polarized lenses that I use as my everyday sunglasses. I take those to the beach, playing sports, driving, etc. they are pretty much my "expendable" pair...if they break or get damaged I don't really care since they are the cheapest pair that I own. Ive had them for 3 years now and they are still in perfect condition except for a tiny scratch on part of the frame from dropping them.
