New rating system

I have decided that I am going to start using a rating system in my reviews.  I feel that this would help me better portray my feelings about the books.  I got the thing about prices from another blog, but I'm not sure which one.  If it is yours, I promise I am not trying to steal it, and feel free to take credit! 

Here is my new rating system:

5-  Amazing book.  I would pay full price for this book.  It is going in my permanent collection and I will probably re-read it.
4- Great book.  I would buy with a coupon.  I would give it away to my blogger friends or readers.
3- Good book.  I would buy from the bargain shelf. 
2- Meh.  It held my attention enough to not put it down, but probably not enough to fully enjoy it.  I would borrow it from the library.
1- Bad.  I most likely did not get through it.  It's not worth buying or the drive to the library.
