I think I've liked every single book and author mentioned so far (including those in the original post).

Also Tamora Peirce - they are YA, but still a great read, I Love the original "Lioness" series. (these books are literally in tatters because of being read so often, I can recite most of it by heart).
Raymond E Feist - Love all of his, start with 'Magician' and work your way through, that will keep you busy for a couple of years.
Forget who the author is (some big name I would know if I saw it), ut "Wizard's first rule" and all of the subsequent books are fabulous.
