I did pretty much the same as Seaview over on the previous page. I went to Office Depot, armed with the measurements of the Iliad. There was a clearance display with last year's calendars and journals outside, but no ruler (I didn't think to bring one). So I went inside the store, grabbed a ruler, went to the journal section, measured out one just slightly bigger than the Iliad -- the journal wasn't spiral bound or book bound, it was just a pad that slid out. Then put the ruler back, went outside, and chose last year's journal! I also bought some velcro.
All told, it came to something like $8 or so, maybe less. I know the clearance journal was maybe $3, and the rest was the velcro.
It protects the screen against scratches, but it wouldn't protect against, say, a well-aimed foot. I dropped the thing in the case from a height of three feet onto carpet, and nothing broke or fell off! That's not a guarantee, just an anecdote.
Oh, and it really looks good. It looks expensive! You can open it up like a book, and the stylus and ports are easily accessible. I was considering embossing something on the cover and spine. Like "Book of Books" in Latin
