I loved the Deadpool movie, and now I need more of that character in my life, where do I go?

What I mean by "where do I go" is what specific comic books or other sources should I look for. I know that a lot of those superhero comics and series have different versions, different origin stories, different styles, and things like that. I've never been into comics, and I know a lot of people think that certain versions are better than others. So what should I get?
