Just thought that I would add to this thread with some (minor) additional information and a correction to an earlier statement.
1) I had an informal assessment of the Marzal done by an area guitarist. While (IMHO) he is steel string guy at heart, he has a degree in classical guitar from Vanderbilt and teaches classical guitar (and other styles). His assessment was that this is a pretty nice sounding guitar (to his ear) that can easily hold its own (sound statement) against used instruments in the $2k to $4K range. In mint condition he would price it at $3k to $3.5K. In its current condition (one repaired and stable, but obvious, top crack and a handful of small marks on the top that are very obvious on careful inspection), he would price it at $2.5K in his shop (where he doesn't regularly deal with high CG's).
2) My wife has a better memory than I have. Earlier I stated that the 1984 purchase price (from the now defunct Guitar Shoppe in Washington, DC) was a bit under $1K. My wife clearly remembers that it was somewhere in the low four figures.
Added just for completeness and accuracy as if you do a search on Jesus Marzal, this thread has about as much information as anything else out there. I would add that if you go to the Dream Guitars website and search on "Builders" using Marzal, there are playing examples on three different Marzal guitars.
