2006 Specialized Allez Sport -
Here's a recent pic in its current state (upgraded just a few things, i.e. saddle, wheels, pedals, bottle cages), but I had gotten the bike for $700 back in August of last year.
It's a solid bike, and I've put 900 miles on her so far. Shifting is crisp (Tiagra FD, 105 RD, Tiagra shifters), and it handles great. I test rode the Trek 1000 and felt that the Allez was a bit more responsive (some may call it twitchy, but I've descended at 40+ mph and didn't feel stability was a problem). Overall, it's a great bike to get into the sport.
