There's many factors that make UWRF a very good program beyond cost, but don't sell the money short. A great program and university at a cost of 10K less than the average MIAC school adds up quickly, especially with the continuous increase of school cost. With years of being very competitive, good coaches, and newer facilities cost is the icing on the cake. Essentially it's like landing a 30-40k scholarship.....hard to argue with that.
As stated cost isn't everything and it depends on the college experience that is sought by the student. For example you couldn't get much different between the UWRF and Augsburg campus's, location, and demographics. UWRF is still a heavy agriculture/education school that pulls from rural areas, and you can't get any more inner city than Augsburg. Both have very competitive programs and do things their own way.
Getting back to the money, I think it's a shame that schools aren't more up front with cost. It's hard to get accurate information until you receive an actual financial aid offer especially from a private school. Those typically come in after a kid is pressured into making a decision. Reason I bring it up, the numbers you provided for some of the schools are not even close to what we just experienced. Saint Mary's came in the least at 25K, Hamline, Gustavus, Augsburg were all around 27-30K after aid, and UWRF came in at 20K.
