I think you might spend $250 at the copy machine. OK, not really, but its a lot of paper.
I have the set for the MY 2000 Impreza... 8 volumes. They total about 6 inches thick. My estimation is its somewhere in the neighborhood of 2500 pages if you print it out single sided.
If this is something you want to do, I suggest finding someone local and copying the pages you want, rather than the whole set. Don't get me wrong, its very useful. But how often are you going to need the 600 pages of OBD II?
