As a UC campus, Davis is fairly similar to all the other UC schools, although you might like what it has to offer more than other UC's. I do feel thought that Davis give a much better deal than most private schools, and with financial aid it can be affordable, even without loans. Overall its not overly expensive, but it is not cheap either.
Its been listed as a good bang-for-your-buck school by some magazine out there, but I was lazy and didn't write the name down of that magazine, so you dear reader will just have to take my word for it. Or not. Its up to you.
