I ended up getting the bike today and glad I did. They guy and his story turned out to be legit. I took the bike to the LBS and they has nothing but good things to say about it. The 7700FX for 2005 is quite a leap ahead in terms of components and carbon forks, seat stays, etc. But at $1400, it's quite a bit more.
It's a gorgeous bike (they thought it was a 2002) and really a pleasure to ride. I honestly haven't ridden a quality bike in many many years, and frankly, it was exhilarating. I hope I never lose the incredible sense of freedom and speed I felt today!
Many thanks to everyone for all your advice.
