Has anyone bought the issues of Mother Earth News 1970-1980 on CD? How do you like it? Also, there is the CD with 1980 to 1990 and articles from the issues of Mother Earth News. I'm thinking of getting these. The cost is $19.95 each. That's only about $40 for 20 years worht of issues. I think there could be some good reference there, espcially the earlier CD's.
