wolf,
for the Class of 2002, 119 were in state and 10 out of state (in MSUCOM's brochure). That is pretty close from year to year. It is really tough as an out of stater, but not impossible. At my interview, they said out of state tuition is estimated to be $32,000 for this year. They do have a few first year scholarships which could help you out. To be considered for these, you have to be accepted prior to the deadline (I think it's sometime in February-see their website). The secondary is extensive. I believe all in staters receive secondaries, but not all out of staters. As part of the secondary, your recommendations must be written on the forms MSUCOM provides. So, consider having those people lined up so you can get everything in early.
Good luck applying this year.
