Manga for Kindle?

[Lephantome92]

I'm eventually getting a kindle, and i like to read a lot of manga. unfortunately, amazon's selection of manga for kindle is lacking, to say the least. are there other legal sources that have manga for kindle? if so, what are some of your recommendations of titles to look into? so far, i've mostly read horror/thriller (death note, hellstar remina, parasyte (not much yet)), but i'm open to trying anything that's available. even if it's not currently published, just thoughts to put on a list for if it does come to the kindle.
