Thankfully educationally there are lots of good choices, even some online options. I went to CSUSM. I got a good education at rock buttom prices. Its not quite as cheap as when I went there, but a good deal I feel. I also remember that all my CS classes were evening and late afternoon, which really helped the working people I went to school with.
UCSD extension can be a good place to start, if you just need to get some credentials to start out. As far as schools, UCSD is the 800lb gorilla in SD, but its expensive and you would have to go full time. Its classes tend not to be scheduled for working adults either.
I am also a huge believer in community colleges. Palomar and Mira Costa both have good classes and help you get back into that college feeling without the full cost.
