They are long out of print, but I still have a soft spot in my heart for the GrailQuest series... a very loosely King Authur-themed series with a much more whimsical and campy style. I remember mailing the author a fan letter when I was about 10 years old, and receiving a very nice handwritten reply from Ireland (which I probably still have tucked in an old photo album somewhere).
