When my Sony T2 started dying last year, I did a lot of research and got a Pocketbook Touch Lux 5. It has a SD card slot so you can side load books you download from DPGroup, supports all types of formats, mobi, azw, even comics. I use Calibre to format books to my preference, but it may not be always necessary. It is wifi capable so you can use Dropbox, surf the net, read news, and it even has games, e.g., sudoku. The Pocketbook supports different fonts and languages and has all types of little tweaks that make your reading comfortable. The reader has 2 slider light settings for reading in different lighting situations so you can set the light that is exactly right for you. It's a great little 6-inch ereader.
