The wife and I pay $300/mo (plus about $50/quarter) for the top-of-the-line plan with CHM http://www.chministries.org/

No, it doesn't pay for preventative care or prescriptions, but we're not avoiding treatment and/or going bankrupt if we get cancer or in a car wreck or something.

Currently these health care sharing programs only exist for Christians as a religious liberty exemption to the ACA, but if we could get the GOPers to actually repeal the ACA I think these kinds of systems could be put in place for lots of people.
