18-200 is quite usefull i think. most people will not be able to tell the difference of photos taken by a budget zoom and a pro-prime, especially when you are not printing less than 10". on the other hand 70-300 is not that useful a lens, and for moving objects, VR is useless, and most people can tell the difference bwtween the pics taken by this lens and a 300 prime, also a used AF 300/4 may even cost you less than a new 70-300vr.
