I applied for India and Hindi. My budget was pretty detailed. I put a lot of work into it, and even if I don't get the Boren, it was a good exercise to get an idea of what my costs will be.
It's encouraging to hear from other ASU students. Unfortunately I didn't work with Dr. Burke because you don't have to go through the university as a fellowship applicant, and also I was pretty late in getting my application together, but I did work with my other professors at ASU.
