If you're making you decision based on the image you posted,I wouldn't bother, I'd do what Chris says and just get the lip.
Grill you can change, get a custom grill made up like the face lift, or just go for the Zunsport grill,
Be a lot cheaper and easier than sourcing a good condition Face lift bumper, along with painting it and getting a good match to the paint on the arches/bonnet etc.
