I've always wondered about this, other than the usual Liang Yu Sheng, Gu Long and Jin Yong books, I think other books should be worthy of mention. They maybe worthy of being produced as series.

Two of these books are Liang Yu Sheng's Kuang Xia Tian Jiao Mo Nu (about a heroine and two guys in the Song-Jin-Liao dynasty) and Wu Lin Tian JIao (which closely related to the first one). Huang Yi's Po Sui Xu Kong is also very good.
