For £800ish you'll be able to get a 2013 defy 1. I am also coming to the conclusion that most bikes by cube and felt are pretty good looking, no idea what they are like to ride though.
+1 for bikes by Cube..a friend of mine has one and he swears it's the best bike he's owned (and he's had a few!!)
Must also put a shout in for Colnago!!!
