Sorry for the delay in replying. (I've not been well).
When providing my original answer I deliberately researched the most recent Canon model compatible with your requirements, so my link above to PC World (which is the same firm as Curry's anyway) is the one you need. (I currently use the discontinued Canon MG5350 and, if it was to pack up, I'd have no hesitation in replacing it with the MG5750, particularly as it's offered at a very attractive price).
. . . and here's where I'd buy my compatible inks from:
