I love Gretchen Bernabei's book Grammar Keepers: Lessons That Tackle Students' Most Persistent Problems Once and for All (Grade 4-12). The only issue I had was with the Keepers 101 Chart - Blank. It didn't photocopy right (too dark), and when it did it was too small for my students' handwriting.
To fix this, I created a much larger (11x17) and fully-typed Grammar Keepers 101 Chart - Blank.
I also have a Grammar Keepers Parts of Speech Sheet - Blank available to download for free.
