Check out N.A.S.E.
They have a great medical insurance plan.
They actually refund your premiums after so many years if you don't use the policy!
I had a policy with NASE 20 years ago and it sounded like a good deal on the rates although I was never sick so never tested their claims policy, but then after a couple of years they were sending out erroneous information on which kind of insurance I had with them, and I could never get a human being to talk, to so I dropped them. I wonder if they have gotten better since then.
