Can you tell me what is the best health care plan for family of four?

Best you can afford.: Usually price will vary with benefits. Try to get a family plan with a relatively low deductible. At your age, you're at low risk for major medical condition, which means if you can't afford 'the best'. Go for something that covers for Oh, Oh moments, and cover your medical expenses out of pocket. Make sure your local doctors/ hospitals accept the insurance..
