What are some affordable introductory neuroscience books?

[Stratosphere]

I'm looking for an introductory neuroscience book. I only know basic biology so I'm not sure if I'd be ok in reading a textbook (I do have the whole internet though if I come across something unfamiliar). I've seen several books however they seem geared for medical students instead of actual neuroscience students.

I found this book but I'm not sure if I have the required knowledge to just pick it up and read it and I'd like to find something cheaper.

The interface for reading isn't good, but it's free:

I'd like a real book though. Do you know if I'll be able to understand the books with hardly any previous knowledge?

Edit: I guess I should add that I have a basic understanding of chemistry.

Do you know of anything cheaper? I wouldn't like to spend more than $80.
