What is the best health insurance to buy?

Of coarse it needs to be reasonably priced and must cover vision and dental.
--------------------
Then you are out of luck. Dental alone will cost you 200 a month. The cheapest insurance is one with a high deductible, high copay and only covers major medical. routine dr. visits are NOT covered. Unless you are willing to spend 1k a month you will not find anything. Check your state's website. Many offer group rates
