Woot.com has the refurbished Sony Reader Pocket Edition PRS-300 on sale for $110 (plus $5 shipping). This is considerably cheaper than the usual $200 price, even with the shipping charge. Take your pick of color--silver, black, or red.
We like the Pocket Reader for its portability, intuitive controls, and comfortable case. It sports a 5-inch, 8-grayscale E Ink screen and supports PDF, TXT, RTF, and Microsoft Word (.doc) files as well as commercial e-books. Because of the limited font-size options and lack of audio support, this may not be the best e-reader for the visually impaired.
