In the end, the school brand can only do so much for you. It's all about what you make of the education. UCSD IR/PS itself may not be world-renowned like Columbia SIPA, but I think people forget that it is a part of the reputable University of California system; which is nothing to sneeze at. Ultimately, you would be better off attending a school where you have a chance to build a relationship with faculty and your cohort. The relationships will matter more in the long run than anything else.
On the downside, the entire UC system suffered a setback because of the California budget crisis this year. So it's very likely that the tuition at IR/PS will rise this year as well.
Also keep in mind that San Diego is the complete opposite of NYC. If you like to live in a big sprawling city, San Diego won't offer you that. It's a little house on the prairie compared to NYC... Suburbia at it's best, but you have temperate weather all year round.
I've had a chance to talk to a couple of IR/PS alumni on the east and west coast and have found their starting salary to be in the 50s.
