Ronso,
I've been in a similar situation like yourself, although I wasn't a pledge or anything. I was interested in a sorority, loved the girls, great organization, spent alot of time with the girls (before and during the time I was interested). All in all, I was really impressed with the sorority. In the end, I had to part ways, because although locally things were great, I learned somethings about the organization and its beliefs that didn't mesh well with me (religious reasons). I still think they are a great organization, taught me alot about greeks (I really didn't know anything about them before hand), but I don't regret my decision. Now I am currently pursuing another organization happily.
My advice to you: RESEARCH thoroughly..both locally and (inter)nationally. Give the orgz on campus a chance.
Good luck on your search
