I really want/need to start my manga collection. I just have really enjoyed anime and have primarily stayed with that medium. Though, for such titles as Claymore, I read the manga online because it's awesome and goes further than the anime (I really wish a second season would be made).
As for Berserk, I have obviously heard of the title but haven't gotten an interest in checking it out. I'll have to ask the opinions of my anime friends.
