I picked up the 2004 FAR/AIM at Oshkosh this year. Gleim was offering a new flight bag size for only 12 bucks. Not a bad deal, and it's in an easy to read format with color inserts for the AIM graphics.
I checked out Gleim's version and the size of their "flight bag" size is 7" x 9" and the 2004 is available. I've been using ASA's version and it's a tad bit smaller.... 6" x 9" but it (2004) doesn't appear to be available yet.
