Well, as you know... I have a Cervelo. I really like it. Although, it wasn't like I went shopping and picked it out of a line-up.
My friend recently bought a Kuota K-Factor and really likes it. She got a full carbon bike for around $2,000. Not sure about the components, but I saw that is has a Dura-Ace/105 mix. Seemed like a great deal for a nice bike.
Good luck on bike shopping! How very exciting!
