What cost difference?

Back then it was a factor of two, IIRC. Also you need to subscribe to an area,
consistantly. With NOS, you can pick and choose, and skip it altogether when
you're not flying any IFR. Jepp was subscription only - and you had to file
all those revisions every two weeks.

NOS is available everywhere. Jepp (if it's available a la carte) is not. So
I'd rather fly what I know, and nowadays, NOS isn't bad at all.
