If you wanted to go with cheap shades I would recommend Flying Fisherman brand. For right around $20 you get a pretty decent pair of polarized shades and you aren't too broken up if they do fall in the lake! The only downside is that the lenses do scratch pretty darn easy, but for $20 they are worth it IMO. I do also have a pair of Oakley's that I love too. But, unfortunately, I am one of those guys that tends to lose sunglasses often so the Oakley's don't make it on the boat very often!
