I'd look at the Astak PocketPro before making too many decisions. It's the same size and price ($199.00) as the Sony 300, but its processor is twice as fast and it has an SD card reader, eight levels of grey scale, a removable battery, text to speech for some formats, and an mp3 player. The PocketPro comes with a real case, the adapter necessary to charge from a wall plug, ear buds, and an SD card loaded with books. (The SD card is provided for orders through Halloween.) The rocker switch on the side looks like a handy way to turn pages. It works with Adobe Digital Editions and several open formats and supports folders.
According to Astak, they'll ship to international addresses for a $30 shipping fee. Even with Customs, that should less than the 300.
Mine should be here next week.
