You may want to consider a High Deductible Health Plan (HDHP), which generally offer lower monthly premiums for a higher deductible. This reduces your monthly cost but should something happen, would require more paid out of pocket before insurance contributes. The main benefit is a safety net in case something serious happens.
Additionally, with an HDHP you may be eligible for a Health Savings Account (HSA), which are tax advantaged savings for medical coverage, reducing your cost of care.
If you're interested in HSA's I have blogged on their benefits[1] and wrote a web app to track your HSA spending[2].
