Selling a Picasso-IV without the packaged scandoubler is like selling a car without a rear view mirror. You can see behind you by sticking your head out the window but it doesn't make things particularly user-friendly and you'd expect it to come with the car!
The P-IV's scandoubler/flicker-fixer is renowned for it's superiority to every other on the market and the fact it was included as part of the board OEM is the reason behind it's high review scores, reputation and resale potential.
Just because the picture didn't show the scandoubler snap-off doesn't mean this is binding. It is taken for granted that this is included in a P-IV so how is one to know which section is missing from a board the size of a shoebox?
