Depends on the condition of the camera and the shutter count. I'd get the brand new one if I had another lens to go with it, because those 18-55s are rather poor but OK for messing around. But you can pick up a 50mm 1.8f which is very handy for no more than 200, its a must have lens basically, it can produce awesome shots. I'd get the brand new one, A. It's brand new so has warranty. B. You won't have to worry about it crapping out and having to fork out a G for a new one. C. If I remember rightly Those 18-200mm Lenses suffer heavy lense distortion at the longer end of the range which is a tad annoying in shots with straight lines, had one for a while over seas and it was very frustrating shooting architecture and getting curves in the buildings where they have straight edged lines.
On another note, got my 24-70mm F2.8 Sigma today....
