Premiere Magazine's Top 100
Here is an even more condensed list than posted here on popfestfast, where I got this information from in the first place. (Note: for the most part, anything in (parenthesis) was from the original post as well) :D

001) Bae Yong Joon (Winter Sonata, Legend)
016) Shin Dong Yup (MC, host of Explorers of the Human Body, 8 vs 1)
018) Rain/Bi
019) Yoo Jae Suk (MC Yoo)
044) Yoon Eun Hye (Coffee Prince)
049) Kang Ho Dong (MC)
059) Kim Yoon Jin (actress on Lost)
065) Jang Dong Gun
072) Lee Hyori
077) Jeon Ji Hyun (My Sassy Girl)
092) Dong Bang Shin Ki
100) Seo Taiji

I wrote this in a comment from the original post:

Jeon Ji Hyun's recent Korean releases haven't had the success of "My Sassy Girl". Her last movie "A Man Once A Superman" seemed to be shrugged off (from my pov) and "Daisy" flopped apparently. I think she's trying to shake off her "My Sassy Girl" image but it's difficult when she got to where she is because of it and it was her biggest role.

But I think she's on that list partly because of her US debut this summer with "Blood: The Last Vampire" :D
