I'm cheap too. But if I got assigned a reading list for fall now, I would try my best to get hold of the books for free (from the library) or borrow them from anyone I know. My main issue is that I still feel there are so many things I don't know about the literature, and so many things to learn, that I'm not even waiting for a book list, I'm just going ahead collecting articles related to my field and just reading them...for fun.
I guess it really depends on the person. For me, I didn't work really hard as an undergrad and spent a lot of time doing every other thing I wanted to do, so I guess now is the time for me to catch up on my feelings of not knowing enough. I know that in the business of research it's normal to feel like I don't enough but I just want to decrease those feelings, even by just a little bit. Plus if I can get hold of the reading list, I can work on the parts I will have problems with, which will make the semester much easier for me, coursework-wise, so I can get going faster on research.
But that's just me, because I've had my fun.
