Keebler is another option since they label for shared equipment and nuts. (I don't know about dairy and egg - the cookies seem to be very consistently labeled for dairy and egg but not sure about the crackers.)
We have eaten the Keebler Townhouse Regular and Keebler Townhouse Reduced Fat (not the Pretzel ones, they have milk in them) a lot with no problems. There's also a few nut-dairy-egg free versions of the Keebler Club crackers and the Keebler Club Mini's.
Enjoy Life just came out with a line of chips that is Top-8 free. I've never seen them in stores, though.
