I strongly recommend you to go for UIUC. As you said, UIUC's accounting and finance are very good and its network in Asia is also strong. Some of our Asian students who graduated last few years ago found decent jobs through alumni connection. I just checked UIUC MBA's group in Linked in and found out that we have many alumni working as managers/directors in companies such as Johnson & Johnson, P&G, McKinsey, GM...etc.
As for tuition, I believe the amount of tuition you'll pay is about the same as ASU after the deduction from scholarship. $15,000 is a lot for UIUC's admitted students. This indicates that UIUC strongly values your ability and believes you have potential to prosper in the future.
