Question: Add on Telephoto Lens for Nikon Coolpix P80

I have this camera and LOVE it. I'd love to add onto the telephoto zoom lens to zoom in for more of a long distance shot or closeup shot, along with a wider angle, but don't know if Nikon Nikkor add-on lens are available for this camera. Anyone know? I see them for sale on ebay, but don't want to waste my money on junk.
