need advice on ground school book

I used Jeppsen and really loved the book but can't speak for the new one
that is out. I do know they have an excellent weather text out now (a
bit pricy but worth it) that I just bought for a friend.

For my advanced training I used Kershner which I would recomend. He has
a private text out too which is probably just as good. His writing
style is humorous as well as informative so he keeps you reading and
learning rather than falling asleep.
