Hello,
I have used Manan Shroff NAPLEX material....I believe it was combo pack 2. It has about 3 books and 7 cd roms. I just studied from it and passed exam with 119. I have also heard few other books like Rxprep, prontopass, Appleton Q &A, ASHP book and Passnaplex now. I have used Manan Shroff material for FPGEE which was extremely helpful so I stick with him for NAPLEX. My advice is whatever source you select just stick to one or two source otherwise you will get confuse.
Hope this helps.
