Did you check Fastlane? They have them for all of the applications for which they are available, I believe. $116 might seem like a lot but it's no more than the set of individual service manuals would be in print were that what was available. But you might, in that case have the option of purchasing the relevant sub-sections covering what you need now, as opposed to buying them for every system at once. I think I've seen "pre-owned" ones in the classifieds here on occasion as well but don't recall the application.
Be thankful they are available at all as they aren't for some!
