All these Cervelo's
if you've got an unlimited budget get something that is at least a little more unique. Pinarello would be great a Montello could rock any TT, and a Dogma FPX is just unbelievable IMHO. The suggestion of a LOOK 595 also excellent. Other ideas include...
BMC Time Machine - SO hot
BMC Pro Machine - You can get it to 13.4 lbs with Lightweights, nice
'08 Madone - This diverges from my "unique" bit but they're still looking pretty cool (mmm 6.9)
Lastly go for a Vanilla bike if you have the cash to not only get the bike but jump the que. Sacha does some wonderful work and that'd be a bike for the ages.
