The Nikon D80 does not have antishake or Image stabilisation
The (costly) Nikon "VR "lenses have that built-in and would not sell if the cameras had that!
This similarly applies to Canon who also need to sell their IS lenses
Doesn't stop Nikon and Canon selling by the shed load
The DSLRs that do are the Sony A 100, A700 and Pentax DSLRs K10D K100D and the earlier Minolta Dynax ( which the Sony replaced). It is a feature that is great to have
but
Does it affect its performance? No..in absolute terms
However to quantify that answer objectively you have to understand in which way IS matters.. or not.
Camera performance not measured by solely by the ability to to provide anti shake even if that allows you to use very low shutter speeds or get images in poor light without needing flash ect
However that is not a subject for this thread
The D80 justifiably very well regarded and a cut above the "budget" DSLRs being ( in a way ) almost in a class by itself
If you do a search on here ( it has been discussed on very many threads in the past and still gets the thumbs up) or go to
DPreview it will be clear from their reviews how well they think of it
Go on to flickr and search for images by camera... you will see what users of the Nikon D80 have been up to
As for buying it in Currys, That TBH is not where I would buy a camera unless there is a justifiable economic reason ( ie vouchers) for doing so
