Hmmm....I think Gaz has the right idea there. If you want the high-end group, you can still run lower-end chain and cassette and keep the running costs down. I have two bikes with nine speed Ultegra, one with Veloce and one with Athena. It all works well, though in terms of shift quality etc the Athena is definitely ahead of the Veloce- harder to compare across the marques, the Campag shifting 'clunk' is not to all tastes and though I'm used to it, using the brake lever as a shifter on the Shimano setup still strikes me as weird. Ultegra ahead of Veloce, though. I went with Athena for the Viner as I liked the Campag feel, the advantages of 11 speed seemed worth it to me, and all the reviews basically said it was clearly the best bang for the buck in their range. All the talk of 11-speed being higher maintenance and needing more fettling etc has not been my experience- it's been no trouble whatsoever for me in 4k + miles.....
Assuming you're thinking of whatever new road bike you buy in the end: Athena, Ultegra or Rival unless you get a killer deal on a higher spec group.
