Should I go to the University of my choice, or settle for a state school just because the money isn't available right now?

I’ve been accepted into a top University in Scotland, have obtained some financial aide, but I’m about $12,000 short. There is the possibility that I can defer, but there are no guarantees that they will defer me for another year. Common sense tells me to just settle for a state school, but I won’t be able to get the same degree, I’ve taken some classes at the state school and found that I knew more than the instructors. I’ve always wanted to go to school in Scotland. I’m not interested in just getting a degree, I want to be challenged academically. Do I give up my dream and settle for less than I want? I have to make a decision by the end of the week. Getting the funds in order by Aug. seems impossible, but the thought of settling is depressing. Any thoughts, ideas or comments would be appreciated.
