I have never taken the NET, so I don't know if you can use the NET book. I have taken the TEAS and I did buy the Mcgraw HILL book for 20$ at Barnes and Nobles. My school library keeps copies of the TEAS study, we are not allowed to check it out, but we can make copies of the sections that we need and thats what I did because I wasn't going to spend the money on that book. You can also go to this website www.testprepreview.com which is very helpful. Using the Mcgraw Hill book, copies of the TEAS book and the website I was able to get a good score and I start the nursing program in January. Good Luck!!!
