Sangh, I think eardocsavvy is right that you should try to visit MSU's program if you can. Talk to current students and see if they are happy with their education. Find out if they feel they're getting a well-rounded experience, particularly in terms of clinical placements. Ask them what they would do if they were in your shoes--would they go to MSU with funding or would they choose the other program?
And remember you may still end up with a good financial aid package from FAFSA, if you applied or are applying soon. (And speaking of FAFSA, does anyone know when we find out about that? I have no clue how it works.)
Also, you might want to get in touch with your other school (which one is it, by the way?) and tell them that you desperately need an assistantship. Who knows? Maybe they will be able to scrounge something up for you if they think they may lose you to MSU.
Oh, and I haven't decided where I'm going yet, but I have it narrowed down to Northwestern and Vanderbilt. I have already visited Vandy, which was great, and I'm heading up to Northwestern on April 2nd to help me make my final decision. Can't wait to make a choice!
