Good Ethernet CAT6 Connectors

I'm in preparation for wiring up my house here in the UK so have bought a 150m roll of CAT6. To test my skills I made a couple of short cables but used some Maplin connectors... these were sh!te. Didn't get the satisfying click sound as I plugged them in. They stayed in but didn't feel very secure. Anyone able to recommend some decent connectors? 

Also what's the best way of colour coding my grey cable? I assume just using coloured connector shields?
