How much does a government employee typically pay for family health insurance?

I recently accepted a job for the federal government. I know that family health insurance will vary from state to state, but does anyone know the cost for a federal employee in Tennessee?

If you will go to www.geha.com it will lead you through a bunch of steps to get to the 2010 rates. Look for the purple line "GEHA's 2010 rates and benefits" on that first page. My mom had GEHA and it was very good. Excellent service.
