Image quality will be a lot beter then the 18-200 VRII. , but keep in mind that it has no VR so you will need faster shutter-speeds.
I bought my 80-200mm f2.8 AF-D, 2ring version. for 500 euros last weekend. the 80-200mm f2.8 AF-D, puch-pull version was selling around 300-350 euros depending on the conditions.
