Somewhere around here someone linked a copy of the LRB that has all the errata photoshopped in; as well as the army updates.
Printed out isn't ideal, but goto an office supply store (Kinkos, Staples or office max stateside) and they can laminate the front and back covers, and spiral bind it. Generally around $10.
If you don't have a two sided printer, or a color printer, it can be worthwhile to use those features to.
I plan on doing that next week for the January Tournament.
