Goodkind is AMAZING. I just bought Phantom (book 10) the other day, (actually, Tonks commenting on SoT reminded me that Phantom was scheduled for release in summer 06, so I looked, and it was available, so I just had to get it), and it's excellent.
I find Goodkind to be a very good author. Some of his books can become -very- depressing, but it's preferable to a false sense of hope. There are times in the books where you feel that the good guys just CANNOT win, and when they pull through, it becomes much more rewarding. A lot of books lack in that area, where the characters only reciever minor setbacks and never lose hope or question themselves.
Dark Tower series is also VERY good, I read them all and liked them all a lot. Insomnia, however, I thought was kinda tedious and mostly irrevelent.
If you really want to get started on a rambler, read Robert Jordan. I swear, by the time you hit book 15 in the Wheel of Time, there are SO many major characters that it's impossible to keep track of them all. Jordan does, though, which results in an 800 page book covering about two days' worth of events each for all of the ~100 major characters.
