Just make sure they are waterproof. I have a cheaper set of Nikons and they are very nice and are very clear. Unfortunatly they fogged up on me this year in the rain. (The rainy day I shot my buck actually)

Its $21 to fix them too. However sisnce they are not waterproof in the first place I didn't send them in. They did clear up later though and are fine now. I just don't trust them for a trip now.
