Convert it to an IR camera. I love IR photography and I'd get one soon.

You can also use it as a backup. If you're like me, you won't sell a camera which gave you a lot of memories already. At best, if it were me, I'd look for a person who's totally in love with photography but is unable to do so due to lack of funds. That way, your camera will still be cherished till its life's end.
