Ask HN: Active incubators in Southern California?

I've found several incubators' sites in SoCal (LA and Orange County), but have heard conflicting things about how active they are. Some have told me they're sort of defunct, or not accepting new applicants, etc.

I'm curious about which incubators HNers might recommend down South. Not going to list what I've already found since I'd like to see what else people suggest. If anyone's enrolled in one, I'd love to hear a testimonial.
