If you waste your money on anything but Nikon lenses, you will be
disappointed, especially if you go with Sigma.

Not true. There are some very good Sigma lenses in the collection - the
70-200/2.8 and 12-24 spring to mind. These offer an excellent
alternative to someone wanting something better than Nikkor's budget
offerings, but not able to afford/justify the premium VR lenses.
Certainly with both these Sigma lenses the majority of reviewers regard
the optical and build quality as excellent. The vast majority of Nikon
D70 owners would be delighted with these lenses. Nikon lenses are
great, but don't let brand loyalty blind you to other excellent
alternatives. This does not apply to all Sigma lenses - as always, do
your research - but there are some gems in the collection, perfect for
those looking for a mid-price lense (ie. around $1000 rather than $300
or $3000).
