I have not used HOD before. I've looked at it, but never thought it would suit my needs. However, now I'm looking at it for my ds10 for next year. He will be in sixth grade. I think it would be a great fit for him. I would like the Economy Package with Shakespeare, the Science Add-On, and the Bible study materials for boys. But, wow, the expense of all that adds up! How hard is this particular year to find used? Or how difficult is it to piece together? And is it worth the expense to buy it new or the time it would take to piece it together? Thanks.
