I just looked through your list... it seems, that you like action dramas. In that case, I would also recommend you:
Iljimae (very intense drama, historical)
Special Affairs Team TEN (its new, i saw a few eps, its not bad :))
H.I.T. (my love, very good detective-action drama)

Hero (Lee Jun Ki again, lol )
Life Special Investigation Team (funny and interesting)
Little Girl K (someone suggested it already, and i would definately go with it, its a jewel :))
Once Upon a Time in Saengchori (yeah, there is a love triangle - or even more, but its more about fun and mystery)
Vampire Prosecutor (definately interesting and dark)
When It's At Night (romance, but pretty decent and interesting, plus there is Kim Sun Ah in it :D)
Secret Investigation Record (weird mix of sci-fi and history O_o)
Keizoku 2: SPEC (japanesse, but definately cool and interesting)
hehe, lots of dramas to consider :D
