I started the post-bacc at SFSU this semester, and it seems good so far. You actually have a fairly early registration time for your classes (already having a degree gives priority over lower division students), so I had no trouble getting into any of my classes. I have a couple of friends who are finishing the program and they've had great success getting into some great med schools (UCs and otherwise). The profs seem very good, and there is a big post-bacc community.
FYI--there is a chem entrance exam to get into general chem, so you might want to start brushing up if it has been a long time. There is also a general math exam (think trig functions) to get into the general physics class.
Also, in case anyone is interested, UC Berkeley Extension is starting a post-bacc program in the Fall. Apps should be out in April. Check out:
http://www.unex.berkeley.edu in the Sciences area for more detail. I went to an info session--these classes will all be held at night and on weekends, so friendly to working adults. So, more options in the Bay Area!
Good luck to you
