I went to Columbia. It is a great school. But if you're currently working in financial services and only view law school as an investment, I really doubt that attending at sticker (even if you get in) would be wise.
I think this is probably a good justification for using my new calculator: viewtopic.php?f=1&t=280704
I don't know the particulars of your financial situation, but I suspect if plug in your numbers, you'll find that law school is probably not a good investment for you at sticker price.
Of course, if you really want to be a lawyer for nonfinancial reasons, then that's an entirely different calculus.
