I bought a 6" one last year for $400. Sold it a month later for $400. It was in pretty good condition, no box or papers. It was a case of I didn't know what I was buying and didn't know what I was selling. I would have kept it otherwise.
I saw one for $1300
here they called it black end...I thought it was midnight black...
one I owned about 90-95%
