A few hundred? Try $800/month which is the cheapest plan the ACA offers where I live. And that plan was total garbage, didn't cover half of what you'd expect and had huge co-pays.
The problem with ACA is that it MANDATED HMO's... Not health insurance. Some people don't need an HMO... if you're running a moderately successful home business you're usually making enough money to cover your families medical expenses out of pocket. What you couldn't afford is catastrophic injuries like car accidents, cancer, heart attacks, etc... So you'd get a very limited policy for that. It wouldn't pay for prescriptions and such but if you started getting $200k hospital bills it would kick in. Those plans were pretty cheap... in the $200/range.
ACA made those kinds of plans illegal. Now you have to buy plans that cover all those things you didn't need... and they cost a fortune. If I tried to get the plan I have with my employer through the ACA exchange it would be over $1600/month. That's insane! And yes, I actually looked it up.
Ironically, one type of small business is flourishing because of all of this. My best friends father is an insurance salesman. When the ACA passed he was terrified... he'd go out of business. He's an older, cranky, eastern European man and hates democrats so that made it even worse. But when the reality finally dawned on him and everyone's insurance policies got canceled, he suddenly LOVES Obama. You see, he makes a commission on insurance sales. Because all of his clients now have to re-sign up for their insurance, he's basically making back all the money he already made off all of his clients the first time he signed them up.
