Deciding which school to go to - SFSU, UC Irvine or UC Santa Cruz?

I got accepted into all 3 of these schools and now comes the hard part - deciding which one I should go to. Financially, SFSU is the school that won't get me broke. The school also has a good reputation in the social sciences and humanities, which is really the only field that I'm looking at. UCI and UCSC are also good schools but their tuition and room & board will drive me broke. I wouldn't consider the financial costs if it was UCLA. Anyway, the great thing about SFSU is that they've offered me the presidential scholarship. The only negative is that I've heard that it's hard to get cles there since there are not enough cl sections offered.
