When it comes to health insurance, I recently had to get some for my fiance and son (I have mine through work). The cheapest with good coverage I found was with Blue Shield. It's about $200/month for the two of them. Plus, the plan I have allows them to go to any doctor they want, you don't have to sign up with one specific one.
I have lived without any type of health insurance for most of my adult life. Thankfully, I've been very healthy! I've been using a discount medical plan for 5 years now and it is worth it if you can't get anything else due to pre-existing conditions or just can't afford traditional insurance. I pay $39.95 per month for my whole family and it includes real discounts on our dental and just about every other medical visit and tests too. I now sell the plan but was a member long before I started selling it. :)
