I second LabRat's advice with great fervor! I went to University of Iowa, (my pops also taught there and did some research for the PoliSci dept until recently) and I constantly and consistently recommend it to others. It's a fantastic university, great programs, etc.
My one main selling point would be the campus and the student body.
There is no real campus, all the buildings are dispersed throughout the town, so you walk around the down town area to get to class. Also, (and I'm sure this has
nothing to do with your decision), but I've been to many a campus, and never found one with the party atmosphere that Iowa City has. It's a whole other planet come Friday night, not to mention just about every type of social group you can imagine (hippies, of course, being my favorite). Plus, dollar pitchers is an
ok deal in town...
...not the most responsible reason to choose a school, I know, but something you won't find listed on the webpage.
