On a red bike, the new FSA Gossamers on sale at nashbar may be a value....They're grey with red accents.

I believe the 7400 series calipers were single pivot, at least mine were, and the 7700 are dual pivot.
However, they could have changed during the 7400 years, since the 6400's did, too, from single to dual pivot.

For value, the dual-pivot polished 105 9-sp series and Ultegra 9-sp series can be had fairly reasonably.
For about the same price, the Tektros and the FSA's are out there, too, new.
