Choosing between Wharton/Booth/Kellogg

(re-posting here since I realized this section exists - from Wharton thread originally - please vote above)

Hey guys

As the dust has settled, I myself with admission offers from three schools: Wharton, Booth and Kellogg, and am very grateful to be in this position. However, the decision is complicated by the fact that I was really hoping for some $$$ not having much in savings and the fact that the max loan I can get from these schools will be 80% of 200k, so still need 40k in cash (and not including other expenses which obviously accrue over time). (btw, 80% is the limit if one is not a US citizen or permanent resident)

First of all, if the goal is to work in investment management or PE/HF, which school(s) would you guys pick (assume being agnostic about location or culture)

Secondly, is there anything I can do to convince these schools to give me some scholarship money? Even 20k would make a huge difference in my ability to attend business school. Does anyone here have experience in or has heard of others that has negotiated some $ from any of these schools?

Thanks everyone - really appreciate any information you can provide
