I'm more or less decided, as well. I've got three fully funded offers right now, but I'm 99.99% certain I'll be headed to UNC Chapel Hill this fall. (Depending on whether or not I get any admissions - and funding - from Michigan, Chicago, or maybe Stanford...extremely unlikely!)
I'm basing my decision almost entirely on the program, which has some really established names in my field, is ranked #10 in the nation for European History, and will prepare me really well to be exactly the kind of historian and professor I want to be someday. Everyone there has been really kind to me throughout the process, and the grad students I've written to have confirmed the collegiality of the department and the sufficiency of the financial aid package...plus, I really want to get out of Texas, and Chapel Hill seems like an awfully nice place to live!
