Okay for your stats of $55k, single, in Cali I found a gold plan:
$235/mo
$0 deductible
OOP $6350
Personally, I think's not bad at all.
Bronze plans have a high $5k deductible and higher copays. $175-200
Silver plans have $2k medical deductible and copays between the two, but $225 which makes it bad vs the gold plan for $12 more a month.
Hell, the platinum is $265/mo, no deductible, with $20/40 copays and $4k OOP max and $5 generic drugs.
