If you live in one of the qualifying states (CA is included), http://www.tonikhealth.com has fairly reasonable quotes for "catastrophic" insurance -- $77/mo for their base plan.
I was going to do Tonik ended up being advised by a professional not to. The important thing with all these cheap plans (I have one now around a $100/month) is to make sure they don't just cover generic. If you get really sick and need special drugs--which don't have generics--you're out of luck.
If you live in CA, I'd recommend talking to someone at allhealthplans.com. It's free (the insurer pays them), and they have great information about all the competing companies--no bs, excellent help. I've sent lots of people their way.
