Aaron at Bicycle Trip really helped me out. We took my 2007 Giant TCR C2's Shimano Ultegra components off of the broken frame and installed them on the frame from a brand-new, never built-up 2008 Giant TCR C3. Same exact frame, but nicer colors. The C3 has the lower-end Shimano 105 and Tiagra components. But I will be using them to build up a new bike, using the broken frame, now repaired by Calfee (was going to sell them but changed my mind).
Here is a photo of the gruppo:
