Note also that code of average architectural quality will require about 1 maintenance day per year per 80 LoC just by virtue (vice?) of existing. (Paul Graham: a full-time maintenance engineer can own 20,000 lines of code.) This is true in my personal observation. I mostly wrote two pieces of software rougly 50,000 lines each, and it's my limit of manageability. Will need splitting up and modularizing if it needs to get larger.
