Linda, I have had the D70s for a year now. Quite pleased with it but not with the lens that came with it but it does the job. Today I was in the photo shop looking at the VR lenses and tested one on the D80. From what I have read in the past year the D200 is the way to go and the price is considerably less than it was a year ago. Her is a good page to get a idea about lenses
www.naturfotograf.com and equipment in general. What ever camera you get it is the lens that counts.
Good shopping and keep us informed
