Had the same decision myself last summer – though with the added fun of finding something with suitable geometry for me at 6’4″.
I think I pretty much considered everything but in the end had a final shortlist of 3: the Trek 1.9, Lemond Alpe D’Huez and the Cannondale CAAD9.
The Trek was first out; the Lemond was a real contender but the componentry put me off; the CAAD9 won out, albeit with a change to a 53/39 chainset and a short rear mech. Although at least then it was a grand – I notice from the above link it’s gone up 🙂
And it rocks. Only thing to be mindful of is if you have a heel-in pedalling style: there ain’t much clearance.
