Free or Inexpensive Grading Books

I’m looking for a free or inexpensive online grading book since my institution does not have any class management system.

Engrade is a free online grade book (gradebook and notifies parents/students). Likewise, HotChalk is also free; it is a grade book and notifies parents/students.

There are a few inexpensive  grading book programs such as Class Builder $39.99 (grade book, quiz maker, and class web page) and Quia $49.00 (has grade book, quizzes, and learning activities like cloze activity).  Even if  I were to pay $49.00 a year, it is a cheap price to pay to have quizzes  graded, have grades calculated, and give students access to their grades.

What free or inexpensive grade book type program do you use?
