I have the '92 FORD Electrical & Vacuum troubleshooting, '92-'01 Haynes & '89-'96 Chiltons manuals, also a '93 FORD light truck parts catalog. However I still want a better repair manual & have not snagged a FORD book. Have seen a variety of CD versions online, but they all seem to make claims that their competitors are bogus.

Can anyone recommend the best of the best in FORD '92 E-150 repair manuals on CD?

Got the impression that the official paper manual was a bit of a disappointment, mixing E & F models, but w/o much detail. What's the best paper manual?
