I worked for an insurance company that provided health insurance for self-employed persons or persons without company paid insurance. www.midwestlife.com
I was terrible at selling insurance, but the jist of the program was that you buy into a group with a nominal membership fee. It offers you a bunch of group benefits like AAA and life insurance. Now that you are a member of the group you qualify for the group health insurance rates. Coverage is a-la-carte so you can build how much you want and the deductible varies.
Based on how insurance works, I would pay for dental out of pocket, vision out of pocket, and select the highest deductable possible. This allows you to be covered against catastrophic medical bills. If you get stuck with several thousand in bills you are responsible for personally, hospitals will allow you to negotiate a payment plan.
Also, I know you have posted that you switched to an environmental job and the pay is less than what you've had before. If you make less than 200% of the national poverty guidelines you may qualify for reduced rates for primary care from a Federally Qualified Health Center - which receives federal dollars to suppliment the cost of visits for low income patients. This way you can also save some money on your doctor visits. Some FQHC's also have dental and vision centers.
Maybe one of these centers is near you: http://www.ci.austin.tx.us/communitycare/chc.htm
