Dave,
I don't think I saw anywhere about what ages you and your wife are. I assume you are younger than 65.
I had planned on retiring in 2012 but found at the last moment that I was going to be denied coverage because of pre-existing conditions (not very serious ones either). I wound up having to stay on my semi-retirement job for another year until the pre-existing conditions portion of the ACA went into effect. I was then able to retire at 62 and got a BCBS bronze level plan for $293 for the two of us after subsidy. It's $5000 deductible, not the best health insurance I've had but it "hopefully" will protect us from getting wiped out by a major illness which was what our goal was. I haven't been particularly happy with BCBS for a number of reasons and plan to switch to another company next open enrollment even at a higher cost. Surely thru the ACA with subsidy you could get coverage for less than $1600/month even in California.
