Where can I find a new remote to replace a hunter

Where can I find a new remote to replace a hunter UC7848 remote control for a BV52 ceiling fan? The Light button is worn out and barely makes contact. Sometimes it won't work at all. You can tell because there is a red light on the remote that flashes when you push any button. All other buttons (Fan Off; 3 speed buttons and a reverse direction button) work fine. If this remote is no longer available, does Hunter make a universal remote that will replace it?
