We chose the Tier 2 option because it was half the price of Tier 1 and we are generally very healthy:
$25 GP
$35 Specialist
$75 ER
70/30 payout
$1,500 Deductible, $6,000 max out of pocket (family)
We also have a "free clinic" at DH's work (GPs and Pediatrician). We can receive treatment, get general lab tests done, and receive many antibiotics and allergy meds free. It can be difficult to get into at times, but we we haven't paid for a prescription med. in two years, only one lab test and two co-pays. It's been great to have.
With the free clinic, the lower tier insurance was adequate and a real bargain. But, we are now looking at surgery for our DD

(see the specialist next week), so we may get a taste of those deductibles and OOP costs very soon. (I feel like I gambled on our health and she lost.

)
If she is a candidate for surgery, we will probably go back to Tier 1 next year. 75% of people who have this surgery, need a second procedure within a year, so we would benefit from the 80/20 payout, lower deductibles, and lower OOP max.
