Page Button apears for logged in users only

Hello, and Welcome all WP Pros.
I am looking for a plugin solution that may not exist. So please read carefully before making a Role Manager plugin suggestion.
I want a page button to appear on the Menu bar ONLY when a user is logged in. I do not want the button to appear at all unless a user is logged in.
I do not want a message to appear that says you must be logged in to view content, but rather a page menu item that only appears once logged in.
Which in this case would be a page with content, or photos for admin etc.

any ideas?
thanks
