If this idea appeals to you check out Alldata on the web.
(http://www.alldata.com/) They offer a CD with service information
mostly derived from the Helms manuals and one disc with coverage of two
cars would cost about $50 as opposed to $80-$120 each for the Helms.
They also have the advantage of being able to print pages of the
drawings which you can then mark up without destroying your expensive
manuals.
