Door Lock Motors

Anyone know where, in the UK, I can purchase the (big) motors for the door lock mechanism on a Mondeo Mk4.

I've ordered one from China, which could be here any time but I'm on my 3rd lock mechanism that's sticking and previously I've taken the motors apart and cleaned them up (and they work) - it's just a bit of a faff.

The motors from China aren't too expensive (~£7) but don't know if they're any good yet. If the print on the motors is to be believed, they are actually made in the UK so if they are made here, sent to China and they can ship one back to me for around seven quid surely I should be able to buy over here cheaper than that.

I know seven quid isn't a lot, compared to the £260 that the units actually cost new, and that's not fitted, nor is it from Ford themselves but thought I'd ask.

Anyway, I've got one to do when my motor turns up, anyone be interested in me taking photos and documenting the process?

I looked previously and could find info and vids on YouTube about taking the units off the car, but not actually replacing the motor in the unit, or the inner workings of the units.
