Flist help? Korean drama

Okay, I'm in such a mood for some good old fashion Korean melodrama. I saw a trailer for the American release of Tree of Heaven and remembered how Stairway to Heaven drove me insane. So, this past month I watched Sad Love Song and really enjoyed it. So, knowing my flist are lovers of Korean dramas, I could with a question:


What are so "old school" Korean melodramas (or epic dramas (think Giant, Seoul 1945) should I be watching?
