We used Beautiful Feet, though more as a book list, since we aren't Christian and I didn't want to use the questions in the guidebook. We also used Guest Hollow's book list, and now that we are studying the Civil War, I end up just choosing books that look good, either from a book list, Amazon, or our library. (I use Amazon to help find books, then get them from our library.) We're doing a chronological study by simply reading good books (and discussing) and not following any particular guide, and it's working well!
I did enjoy using the timeline from Beautiful Feet to go along with Early American History. The other resource that was great was the Liberty Kids DVDs. I've always limited screen time for my kids, but I thought this series was really well done...my kids loved watching it, retention on their part was great, and I enjoyed it, too.
