Expense calculation for universities

I have got admissions in the following colleges

1. University of Texas Dallas
2. Oregon State University
3. University of Central Florida

Please suggest me which is best. I am concerned about the financial matters as well. I heard that OSU is cheap and better than the others in the list, but the structure is as below;

Tuition and Fees = $23,900
Room and Board = $11,300
Books, Supplies and Health Insurance = $6,700
TOTAL: $41,900

This is expensive when compared to UTDs fee structure. In what ways the cost can be reduced. For the complete MS course, what would be the total expenditure and total fee for 2 years? How many credit hours should be completed in 2 yrs? How much amount should be shown for i20 and F1 visa?
Please reply asap.

Thanks in advance
