Don't just look at NOW. Think about FUTURE. Money can come and go, but MBA from a good school is a lifetime asset (what you can learn in school, the friends you make, the alumni network, etc).
this is really a tough but happy decision. I wish I had been in such dillema. I personally think money is abosolutely a factor in decision making. But like most of the poster said, you should look at the long-term benifit not the short-term. However, how to survive in the two years also a consideration. Sorry, just couldn't help you more but congrats!
Just as all the formers said, it is a happy situation. It is good that you have sth to choose from, although to make the final decision is rathar hard. I really have no advice for you on which one to choose, only want to say that whichever you choose, it must be the one YOU choose for YOURSELF. The experience will change your very life, not that of anyone else.
I believe you will make it out. And that would be the one you would never feel sorry for.
