Saunders and Kaplan are both really good. I guess whether one considers the study material good or not is subjective, but honestly IMO, Saunders has very good content material and Kaplan is good for strategy and problem solving. Also there's a couple of apps like NCLEX-RN Reviewer w/Rationale and NCLEX Flashcards app that are pretty good, considering that they're free. If you buy a couple of quality books and use those free apps in your spare time, you'll be good. Good luck to you!
