A 'typical' price for a Level D FFS is around $10M for something like a 737/A320... the Boeing/Airbus data package price for these is around $1M (and must be paid for EACH simulator...). The data package price for the 787 is reputed to be some $8M but includes a significant proportion of the software from the aircraft.
Although there are some reasonable lower priced devices around, there is a reason the Level D devices cost what they do and I don't see that changing any time soon.
