I bought one for $150 this week - it has one extra presser foot - the zipper foot - and it's missing one of the two spool holders. No manual -
It does work - I did try it before I took it home.
It does not seem to be that much different from my old 1962 Bernina 530-2 as far as features and how they function.
Except the old one is that greenish color and the 1006 is white.
