I would recommend getting a new one at Barnes and Nobles or Best Buy. (They both have the same price), but maybe (if you want a cheap price).....Ebay? They sell used ones.

There is no Nook 2 or Nook Lite coming up. There is a Nook Color, which I think has decreased the price of the Nook. But you can check in the Barnes and Nobles website.
