Query: Greatest Zeppelin Transcriptions I've ever owned.

I originally bought this boxed set in 1992 for $85.00, and it was worth every penny. The lead guitar parts are almost all there, the tunings are accurate, and the tablature is complete and accurate. I lost my original set to an irate ex-girlfriend in 1999, and I have spend 7-years searching for a set of the now out-of-print books (2002-2009): that is how highly I think of them. I recently found a used set for approximately the same price I paid for my original set, and I jumped on them. I cannot recommend this set high enough.
