Buy them both. The chip Rack is just Nevada...and the best there is for nevada. But the Official Guide is also an excellent book and covers a larger scope and has pictures. I just LOVE pictures. So you will need them both. If you are serious enough to join the club...you are serious enough to have a good reference book collection to go with it.

Next week...we'll discuss buying Gregs book on Riverboats, Archie's guide for AC chips....and the other 20 books available as well.

I asked the very same question you did when i decided i needed a book. I now have 8 different books on chips.
