His best source, is a local, independent agent.
I'm not sure what exactly he's looking at, as far as determining "value", but if he's 20 and perfectly healthy, no preexisting conditions, $200 should be able to buy him into an HMO with a $250 or $500 deductible.
If he's 40, though, then $200 with no preexisting conditions, if he's not overweight, he'd need to be taking on a substantial deductible - $3,000 a year, at least.
Or maybe he thinks he should get dental and vision for that $200 a month - those are separate policies, and rarely pay out more than they cost.
But since "do it yourself" insurance clearly isn't working for him, he needs to use a local broker, who can explain how it works, and help him balance cost and coverages.
