Does anyone have the new Kanzen Master N1 Goi book (white and blue cover)???

I have the old one that combines 1kyuu and 2kyuu (purple cover) and I am wondering if the differences between the two warrant buying it or not. I'm buying a few different textbooks online and don't live in Japan anymore so I can't go and check it out for myself.

Cheers!

N1 is suppose to be slightly more difficult than 1. It wouldn't be a bad idea to get a book dedicated to one test.

i'm also interested if someone can comment on the other books too, in particular the grammar and reading. thanks.

I ended up getting the N1 grammar and goi books - they were only 1200 yen each. I really wanted the dokkai one but it isn't available yet. It says on the publisher's site it is scheduled for release this month sometime.
