I've a pair of Ocean Waves sunglasses. These are amazing glasses right up there with Costas. I bought them in Tampa a bit back while my eyes were still young. About 2 yrs ago I cracked a lens and called them, for the price of a lens they sent me a whole new pair because they didn't carry the original frame any longer. Their customer service is top notch just as an FYI. Anywho, I've got the Kauai with black frames and backwater green glass lens designed for sight fishing. They are in great shape. One tiny scratch that can't be seen while wearing them and you have to really look hard to even see it.
This is a link to a new pair, $199
$100 seems fair to me, not interested in a trade and not looking to ship. I live in the DFW metroplex, Carrollton to be exact, if you're interested in seeing them send me a PM.
