I just went through the selection process a few weeks ago. I settled on the tokina 100mm 2.8. It reviewed as shaper than the more expensive nikon lenses Tokina 100mm f/2.8 Macro AT-X PRO D AF
You will have to manually focus. It's street price is around $400
the first lens really isn't a macro lens. as the closest you can be to something is 3.1ft to ensure the lens will be in focus. The f stop is kinda poor too the other ones with an Fstop of 2.8 will be perfect.
