Looking to get a pair, but don't want to pay an arm and a leg. Actually, I'd like to keep it under $50 if at all possible. Is that realistic in terms of quality? I don't know much about these past their effectiveness for seeing into the water/cutting glare. What I'm wondering specifically, is there a certain point on the cheaper end where saving bucks is giving up performance? Is there a mid-range at which you get what you paid for? Any links to reviews? And what tints are suggested? Thanks!!!
