Have you checked out the Onyx Boox? I've seen some great reviews for it, it reads a ton of formats (PDF, TXT, HTML, MOBIPOCKET, EPUB, CHM,FB2, DJVU, RTF,PDB, JPG, PNG, GIF, BMP, TIFF, MP3, WAV), and it has search and dictionary support. Here is the wiki link:

It has a wacom touch screen, so the screen should look the same as non-touch e-ink screens.
