MadMax, if you like the Rawn books, you might like a similar series: Ann Marston's "Rune Blade" books.
The best one-volume fantasy I've ever read is Joy Chant, "Red Moon and Black Mountain." It's out of print, but the book's only fault is that it's too short. She was discovered by Tolkein's publisher in England. This is a gem.
The Robert Jordan books (I just finished #10 this weekend) are too damn long, too complicated, and no end is in sight -- although the hints of a final wrap-up are in the latest book. By this point I don't care about any of the characters; but I do want to know how it ends. Of course, it may take another ten books...
The Fionavar stuff by Kay is OK, but I think it's very derivative and unoriginal (King Arthur meets Lord of the Rings). His other stuff is amazing, however. Truly original, beautifully written, and engaging.
Didn't like the Goodkind books (too repetitive and often disgusting), the Rawn books went on for too long and were disappointing (but I read 'em all). and I never liked Covenant. But there's plenty in the genre to choose from!
Add Anne McCaffrey and Mercedes Lackey to the list. While each has written a good deal in their respective series, and the books are uneven, each has written several gems.
