Best bike for less than £600

SeanMannion

Have been looking at bikes for a while to decide which I can go for as my first bike. I want to spend around 600 on the bike itself and think i'm going to go for the Planet X linked here http://www.planetx.co.uk/i/q/CBPXRT58ALUTIA/planet-x-rt-58-alloy-shimano-tiagra-road-bike

However I just wondered if anyone has any other recommendations so that I can compare?
