An update to my cover situation: I looked EVERYWHERE for something that might work and didn't find anything that wasn't too big or too small until I dug up my passport cover. I have a folder style passport holder I got free from Black's photography and it is a PERFECT fit (looks something like this: http://ak.buy.com/PI/0/250/217056435.jpg
). I now have seen some mini sleep covers on the shelves (rarely), but I am definitely waiting for that $30 price to drop. For now the passport cover is an excellent substitute.
Just another option to consider if you are out looking.
