If you do not mind the slight juvinile aspect, David and Leigh Eddings make good books, with fun and interesting characters. Maybe not the most realistic characters, but as EUOLs review showed, its not much fun reading about a realistic but annoying and boring character. Lots of books as well - they did two major lines, one with 2 trilogies, the other with 2 5-book series'. Plus some spin offs and some unrelated books. Actually, has anyone read their latest one?
And Raymond E Feist is good, although do not bother with anything other than the three main series: Riftwar (Magician, Silverthorn and A Shadow at Sethanon), Serpent War (Shadow of a dark queen, Rise of a merchant prince, Rage of a demon king and Shards of a broken crown) and the best one of all, the Empire series which is a collaboration with Janny Wurts (Daughter of the Empire, Servant of the Empire, Mistress of the Empire). His novel Fairie Tale is a good modern horror/fantasy.
