Hmm, a little late on this thread but I am an avid fantasy reader. I absolutely love Mercedes Lackey - anything set in Valdemar. I just read the first book in her Dragon Jousters series & I'm itching for the next book.
My other favorites... any book by John Marco (he's on his third series), my favorite series being The Eyes of God.
Sara Douglass - The Axis Trilogy/Wayfarer Redemption series. After those books, I read Beyond the Hanging Wall & Threshold, which sort of combined with the Wayfarer characters in the Darkglass Mountain trilogy. The Troy Game tetralogy is a sort of historic based fantasy, beginning in ancient times and resuming in somewhat more recent (not exactly modern) times. I enjoyed it, yet appreciated the other series more.
Kate Elliott - her Crown of Stars series follows a satisfyingly complex storyline, including war, romance, politics, and religion (the usual). I tended to skim past her specific details relating to astronomy (mathematici also play a role in the story), but overall I truly appreciated this series. Oh, and readers will observe an impending apocalypse, obviously whether or or not it occurs, and the aftermath.
Tamora Pierce - another prolific fantasy giant, in my opinion. I have only read the books based in The Circle Universe. The Circle refers to four young mages from disparate backgrounds, who form a unique (never before seen) bond which allows them more powerful magic. Of course, the young mages are each accompanied by an accomplished mage (teachers at a mage school) of similar power, so that they learn control, skill, and may become accredited mages.
That pretty much covers my all time favorites

I'm still trying to expand my taste, as far as authors go.. I'll probably be using some of the previous suggestions!
