You can get them a little cheaper than that on ebay, but cheapest I have seen a set go for is around 120.
So far no one that I know of has scanned them, but Reaper did post the pdf of the service manual cd -

It is a little more general than the factory service manuals, but it is good.
I'll move this to the wanted/for sale forum, but I think you will have a hard time finding someone who is willing to sell theirs.
