I had this machine! It was a dream machine for the period! I loved it and used it for about 20 years off and on. Just sold it on ebay recently for about $125 I think - no accessories with it...couldn't find the books, cams etc. - Now I found them! Anyway...I paid $788. in 1979 for this machine. WOW I got a deal I think. I never took it in for a cleaning! Bad - yes?
