It all depends on your situation, but for my family, we've gone with Christian Healthcare Ministries rather than traditional insurance. I'm a Type 1 Diabetic and they covered me from Day 1. The costs for their top-tier membership (Gold) is $150 per month per unit. Each spouse is a unit, and if you have kids, they count as one unit collectively. For our family, my wife and I and our two kids still at home cost $450 per month. It doesn't cover maintenance drugs like insulin, so I'm having to pay that out of pocket. It does pay for medicine related to a specific procedure (antibiotics, pain killers, even expensive stuff if it's just for a period of time to treat a specific incident rather than being something you would take for the rest of your life.) They pay quickly and we manage our health care -- not them.
Had I gone with insurance through the affordable care act, my family policy (this was in 2014) was going to be something like $1400 to $1500 per month with a $3000 per person deductible. We figured we would have spent well over $20,000 per year before we saw a penny of benefit.
I understand Samaritan and Medi-Share are both good options, too.
