Hi StephanieK,
The cheapest copy I can find is from World of Books and is 8.99 pbk, and is in very good condition. However, if you look on Youtube for James Hayton there is an excellent lecture entitled 'How to get through your PhD without going insane'. It's one hour, twenty nine minutes long. Having just looked at as much of the book as I could on the Amazon preview, I would say that a lot of the most relevant material is covered in the lecture. I saw this lecture a couple of months ago and, although I got my PhD in 2006, I actually learnt a few things from it that I did not know! Hope that helps.
