I agree with RRRoger's comment about these lenses in combination with the TC-2 III. Also, I found the VRII had a noticeable improvement with 1.4 and 1.7 TCs.
The VRI is soft at the edges and corner, which might not be a problem for you. The VRII is very good across the lens. The VRI doesn't breath down like the VRII. To me, this isn't a big issue since I don't shoot minimum focal distance at 200, so, the VRII doesn't bother me.
As to the $700 difference: This is $70 a year over the next 10 yrs, which is about how long I owned the VRI. You would assume a VRI purchased today will depreciate faster than a VRII moving forward.
I'd go with the VRII, it is the best buy going forward.
