12 volt resource cd-rom?

Has anyone used their  1979-2007 Vehicle Wiring Diagrams on CD-ROM?  Is it worth it ?  Is the data acurate?  Any better options out there?  Thanks for any info.......

They advertise on this site so anybody who contributes to this site is worthy of mention. Most of the info on the CD can be found on the web - it's a compilation of handy shortcuts/links and info taken from websites. The database was Bulldog but JBS no longer exists. The info is accurate for the vehicles I checked out. Most purchased databases will cost upwards of 50 bucks so the CD is a good buy to bring your data with you on the road if you don't have internet access or wish to use your laptop in different locations. Doesn't compare with DirectWire, Astrochart or Wiremagic.Prepare your future. It wasn't the lack of stones that killed the stone age.
