If you need to save a bit more, try looking at some Russian jets
Safety and maintenance isn't an issue here 
How are Soviet airliners unsafe? Only airliner that is known to be acutally unsafe is the Antonov AN-10, and that one had major structual issues at the wingbase (the cargo carrying sister, AN-12 was found to be ok though and not prone to this.) Like I said in that IL-76 thread, if you actually read most of the crash reports of these soviet airliners, it had nothing to do with how the plane was engineered or built, but rather of a 3rd party affecting it, such as missiles, mountains, other planes, the pilot inproperly flying the plane way past the limits that engineers inteded it to, shoddy maintinance. It is like the DC-10, it had gained a reputation for being a flying coffin, especially between the 70s and early 90s. Other than the early cargo door issue and UA 232, most of that had almost nothing to do with the plane itself.
As for r/l maint, I'm not sure, I know that the older frames are pretty pricy to fix because like almost all planes, as they age, they need more attention, and that there are not many spares avalible for newer frames due to low demand.
