Micra K11 - Faulty injector (easy change out)?

My Micra (non coil pack), started running a bit ropey recently. I changed the plugs and HT Leads, as they hadn't been changed for a while and it was still running ropey. Seemed like on 3 cylinders.
I unplugged the injector on number 1 and the engine speed didn't change.
A faulty injector.
Where is the best place to get one and is replacing fairly straight forward?
Some videos saying the whole injection rail has to come out?

Got the inejctor changed out ok.
Tip I found (mine pre coil pack). Soak the screws & injector head in plus gas for 24 hours and get a decent quality cross head screwdriver. Push hard and turn. The screws will undo without cross head shearing.

Then get a pair of molegrips and gently grab & turn the injector with a gentle pulling action. The injector will start to come out. There is no need too undo the fuel bar and push from the bottom, as Haynes manual says.

All running ok now!
