I'm in the same dilemma. Got a full ride at LBJ, and am deciding between that versus Harris/Sanford/Goldman, each of which would probably come out to something like 40-50k in total tuition/fees unless I can negotiate much more funding (which I'm going to attempt to do).
I really like the idea of living in Austin and also being debt-free, but I'm hesitant about the comparative career bump the school would give me since it's lower-ranked and I would probably want to return to the east coast afterwards. It's a difficult decision!
