Go on competivtive cyclists web site and price out a new S3 with campy 11 record and a srm. It will only set you back $14k for a bicycle.
I rode a slc-sl at a 'velo demo and it was very nice but most bikes will be when set up with Red, 404's carbon bars, stem, etc. etc. Good bikes but not worth 3-4k for a stock frameset.
