Do you have a copy of the Military Tech manuals? They are not copyright protected information. They contain the same data as the civil manuals, only in a military format. It is best to have the civil manuals though. As far as cost, I cannot speak to that, I think that anything under a few hundred bucks is not out of line, but if you are wanting the full maint,SRM, IPC, flight manual, SB, TB, SL, library, maybe even up to 600 is not unreasonable. It is a lot of data to manage and copy and send. True that there are many TC holders who offer such information for free to owners of their product, in the interest of promoting safety, there are also many who do not. They are a private business and it is their call.
