Ribble have been recommended to me and i think for a grand you can get a nice carbon number! I have recently looked for a bike around the £1000, test rode loads including an 08 Specialized Tarmac and a Roubaix (both Carbon), a Trek 1.7, Cannondale Six and CAAD 9, I was looking for a comfortable drop bar bike for long commutes and longer weekend rides (kind of solo sportives).
Eventually I rode a 2009 Specialized Allez Elite and whether it was the actual bike shop setting it up for me better or me just being odd but I found it much more comfortable than the others and I have not looked back! But its don to personal choice at the end of the day, to me it doesnt matter what is written on the side, its about how it feels.
Good Luck!
