Projector - A projector will allow you to show your graphics to an audience, where as if you only had the monitor to show your work, not as many people would be able to view it.
Printer - A good printer would improve the quality of any designes for leaflets and other handouts with brighter colours and better picture quality which would catch peoples eye more.
Camera - A good camera like the Nikon D600 24MP DSLR Camera will deliver outstanding levels of detail and tonal range and will produce great quality photos that you can scan into your computer and use for leaflets or print out as photots.
