There is a discussion group called "Tape Heads" that he regularly participates on, and I was going to relate my experience with him on their site after talking to the site-manager. He appears to know his stuff but has both an attitude problem and a business-ethic problem. Maybe I'll go ahead anyway- I have saved dozens of his nasty e-mails so it could turn into a book.
"SKYWAVE" is his moniker. In any case do NOT EVER send him a vintage machine.
