Amazon has the Kindle DX on sale today for $80 off. This is Amazon‘s 9.7″ E-ink eReader and it’s been around so long that I don’t think it needs a product pitch any more.
If you want my honest opinion, I would not get this eReader. Instead I think the $300 is better spent on an Android tablet. You can install the Kindle app and get most of the features of the KDX, and then you can install more apps and easily surpass the abilities of the KDX.
