Iiyama prolite E2473HDS seems to have excellent reviews, and looks a steal at £148... I'm about to get one myself! In fact, the only issue with it is the stand, which is a bit crap, albeit stronghttp://www.cclonline.com/product/53811/PLE2473HDS-B1/Monitors/Iiyama-ProLite-E2473HDS-24-inch-LED-Monitor-/MON2871/
CCLOnline also do a dead-pixel guarantee for 20 quid more where they'll check to make sure your monitor has no dead pixels at all... pretty awesome!
I reckon this monitor is still a steal at £168, especially as this price includes that guarantee... Everywhere else sells this monitor at £160
