On a side note, in the past I've seen many times where people have discussed the possibility that some Nikon & Tamron lenses are produced by the same factory, including the same elements and design. One such lens is the Tamron 70-300 LD 1:2 macro lens, but it might have only been this specific lens. The design is exact to the Nikon lens produced at the same time.
You might use google to do some research and see what you come up with on the specific lens you're thinking about. Sometimes you can find some very helpful information to base your decision on. There's some pretty old ties that go back several decades with a few glass maker/designers, and camera brands. Lens history is pretty amazing when you look into it, and pay attention to the names involved.
