Maybe that will help. A small fraction of the programs from the list. Some of the numbers might be off so double check them. Most of those have been taken from the program selector. Some of the per credit numbers have been changed to total numbers. Many universities also provide quite a bit of scholarships so remember that when comparing too. In terms of reputation and so on, you will have to assess that for yourself by researching the particular programs.
Research the university extensively. Look through the threads on this forum. If you still have additional questions post them and I am sure the several members on this thread will try and help. I personally will be attending the Illinois Tech program, so feel free to ask anything about that.
