decisions? cost? help?

I am going to be a first generation college student so I am new to all of this. I was wondering which //sororities// would be good for someone who isn't super familiar with greek life? I'm a very social/friendly person which is part of the reason I'd want to go greek. My family is not the strongest finantially so I was also wondering how some of you go about making your payments? Thank you so much ((: I am really looking forward to beginning a new tradition for my family of college and possibly greek life!
