I personally have both for my kids. sons and daughter. I think they are great books. I like all of their materials. I think it would be great if you are not wanting to rush threw something. It is a book that you have to decide what you are going to have them do. You can pick from many different projects to try. Some are more time consuming than others. Some are easier to do than normal. It is a building character book. It has many wonderful aspects. I do very little with my daughter right now because she is only 6. My boys have done more. I think it would be good to try if you have the time in the morning and you are wanting something to study something meaningful. It is quite large so don't let the book overwhelm you when you get it. I have bought some of their other revised additions and I like them better in some areas and I like the older ones too. so, I guess I am not much help there. :) I think the revised editions were more clear though.
What I did was bought the older version on sale. When they came out with the new one I really wanted it. My sister was having problems with her daughters so I gave it to her. Then I bought the new one. I call them directly and asked if they had any blemished one they wanted to sell... Sort of like the Dented can sale. They said sure! They gave me such a wonderful price I couldn't pass it up. They can't do anything with the ones that have bent up corners or miss spelled words so they have them lying around. I do this with some of my books I can't get for a cheap price. I look at what I can get it for on E-bay or vegsource or SCMcurriculum, orhomeschool classifieds. Then, When I call them I know if it is a good deal or not. Usually they are lower then what they are going for on those sites and I get it new.... with flaws of course. One time I bought DVD's from the Maxwell's and the DVD's were good. The case they were in a little messed up but I didn't mind. I thought if it bothered me to much I would just put them in another case... LOL... So you may try that as an option. Don't be afraid to tell them if you don't think that is such a good deal either. The companies are usually willing to work with you...
I hope you find the one you want at a good price. Remember, It doesn't have to look pretty to do it's function!
