Where can I buy cheap digital cameras both online and in store?
Hi,
I need a digital camera for one of my geology classes as we would be going on filed trips-including coal mines, so i would need one that is very good in the dark and take very good close up pictures which I would use in my presentations.
The only brand I like is Nikon and I want a touch screen, but the highest MP the Nikon series has is 12.1 MP, which is the S70. Would that be okay or should I get a 14PM one, the S7000.
What zooming would be best for me? Would the Coolpix series be good for me or should I think of other brands?
Also, where can i get cameras (only new and refurbished) at a good deal- both online and in-store?
Thanks.
