You also seemed to have forgotten Gizmo's site - http://www.techsupportalert.com/
-steeladept
as a newsletter as well ?
Just had a look, great (links) page
re the hardware section
-
Steves Digicams is great site -
Another one I like a lot is
Imaging Resourcehttp://www.imaging-resource.com/If I was seriously researching cameras I would check out both

Would you consider adding online computer hardware stores for UK, Germany/Europe or others?
Cant recommend any personally! (Have used a few but still wouldnt know enough to highly recommend anywhere ... pixmania I used a few times - reasonable price & easy to order with fast delivery in my experience - they're based in France but deliver Europewide I think)
I'm sure there'd be loads of people able to recommend sites here

How about "shopping" sites then -
(is that the correct term - preisvergleicher/price-comparer?)
e.g.
http://www.schottenland.de/ seems to be the best hardware oriented one here in Germany with feedback re the sellers.
