KRYPTONITE SERIES 2 U LOCK WITH 4FOOT CABLE OR KRYPTONITE MINI U LOCK
Price is £19.99 with free delivery over £20 and they have a range of 99p mini LED lights to take you up to over.
Got one of the skull lights http://www.planet-x-bikes.co.uk/i/q/LISLSLEDBL/skull_led_bicycle_light and just as good as a Knog Frog IMO and fits round the head tube.
Good price for a decent U lock and had excellent service from them recently - delivered next day.
