I will be there as of this weekend. I got a lot of financial aid, but no scholarships. Part of it is that I did a community college for 2 years instead of regular high school. In return, I got a degree and enough college credits to transfer to qualify as academic junior at DU. Because of that, my GPA was not weighted like my fellow hsers, even though I had a solid 3.97 at the college. Because of that, I did not get any merits. But what's nice about DU is that they are private, so they have oodles of money to give away. I ended up with about $25,000 dollars of free money in financial aid and increased loan caps.
Although I haven't "gone" there yet, I can say that it's a really good school. It's a top 100 school (based on US Weekly), located in a good part of Denver, and has a quarter system that includes a 6 week winter break. I've also have had a great experience with admissions and the financial department.
CU and CSU are close in price if you live in state. But, I received very little in financial aid from them. Ironically, I'd have to pay about $15,000-$20,000 more than DU to go to either one.
