There are other online brokerages, both large and small, that can help you sort out the individual market health insurance options available in your area. Most of them can show you plans that are available in the exchange as well as options that are only available outside the exchange (no subsidies are available outside the exchange, but as noted above, you're probably not eligible for subsidies anyway, if you have access to an employer-sponsored plan).
As mentioned above, the majority of Americans who have insurance obtain it through employer-sponsored, or group health insurance plans. The coverage has numerous advantages – among them cost (including the government income tax exemption for health benefits), ease of enrollment, and a wide range of plan options. (In addition to a health insurance plan, employees may have the option to purchase insurance for dental, life, short- and long-term disability.) Read here for more details about group health insurance plans.
How do the benefits differ? What would you owe in out-of-pocket costs if you were to be injured or get seriously ill? How does that compare with your out-of-pocket exposure on the employer-sponsored plan? Are your doctors in the network of the individual plan? You'll want to carefully consider all of these things before switching, and keep in mind that you won't be able to rejoin your employer's plan until the next open enrollment window offered by your employer.
