As you already know good health insurance can be very expensive.  The only real way to find out who will offer you the best rates is to comparison shop as many companies and agents as possible.

When choosing a health insurance plan make sure that you choice isn't based only on price.  The companies financial rating is also very important and shouldn't be ignored.

I saw an e-article called Saving Hundreds of Dollars on Insurance that has links to free quoting services who will take the information that you provide on the quote request and forward it to local agents and companies that do business in your area.  Also they show you how to check out a companies financial rating.

There's also a consumer insurance site called InsuranceEasy.org that is very good.  I would use the resources available through both sites.
