I got a pair on ebay for about 90 bucks. Included 4 pairs on lenses and some overdesigned case. They are a little big, but they offer excellent protection. At first I thought they were a little flimsy, but I'vd come to realize that is really a durability feature. The goggles do seal quite well, not as good as swim goggles but definately enought to keep out dust and sand. They fit perfectly in the zippered side pocket of my Fatboy including the extra temple pieces.
