It would be a great name, except for the copyright infringement (olympics). The olympic commettee has a whole legal department that is very active in protecting the name.
Less than reg fee, I'm afraid -- all "olympics" domains have major trademark issues, and the Olympics Committee WILL come after them. I made the mistake of regging two myself a couple of years ago that I only had parked and I got a cease-and-desist letter from them.
Do a search here at NP for "Olympics" and you'll see that you can't own these legally.
