VERY, VERY, VERY few zoom lenses can be used for copy work, unless
you just don't care about quality - not only are field-flatness and
uniformity of image sharpness around the frame issues, but distortion
and illumination evenness are also issues with zooms (which are often
nice compromise-type optics for general subjects, but which are not
generally up to the demanding requirements of flat-copy work).

>A 105 mm macro lens for the Nikon seems quite expensive!! (about $700)

A used 55mm f3.5 (cheap!), 55mm f2.8, or 60mm f2.8 Micro-Nikkor would
work fine (AF is not needed) for flat-copy work - or even an E-Series,
AIS (compact plastic version), or AF 50mm f1.8 would work well (these
have no linear distortion), if the subject size is large enough to be
covered within the normal focus range of these 50's... If you need to
go to 1:1, adding a tube to the 55mm Micro-Nikkor lenses can get you
there cheaply, or the 60mm Micro-Nikkor will go to 1:1 directly, with
the highest image quality of all the choices. I also would suggest
getting an "E" grid screen for the camera (since the camera VF has
some linear distortion, making accurate centering/layout of copy
work difficult).
Hope This Helps
