In my honest opinion, keep the one you have! I have seen alot of broken, and have had a few broken Nikons. If you dont want to believe me look at a Natchez catalog, they have pages of refurbished Nikons, these are scopes that were broke or had something wrong with them and was sent in for warranty work. Nikon fixes them and turns arround and sells them for a little less than the price of a new one and only offer a 90 day warranty on them. Nikon has a hell of a racket going on, they sell a inferior product and when it breaks they get to sell it again, if it breaks after they sold it as refurbished and it has been over 90 days, you have to pay for it, possibly making more money on the same scope that was sold twice. I dont know of any other company that does that! NIKONS ARE A POS!!! IMHO.
