Go to CA Marketplace and get the highest-deductible plan you can find (it will be the cheapest plan as well). You'll be paying out-of-pocket for your doctor visits, but that's what you want to be doing: the plans that meaningfully offset routine medical costs cost more than you'd pay just doing it out of pocket.

If you're both male and you have no prior health history of any sort, you can also go direct to Kaiser, Anthem, Blue Cross, &c and buy private insurance. There will be a medical questionnaire to fill out, and it'll take a little while to be approved, but it will ultimately be cheaper than the marketplace plan.

However you do it, do it carefully and follow up with your provider to make sure you're enrolled properly. Ours screwed up a bunch of stuff (both enrollment and billing) and we have some horror stories about the results.
