Especially compared with the prior situation which was that as a freelancer, if you were lucky you could get individual coverage for around $500+... assuming no pre-existing conditions.
In NY, it was illegal to discriminate based on pre-existing conditions, which meant it was higher there than other states in which it was legal. I used to live in NYC and was under Freelancers Union insurance, which ran about $400 a month with a $10k deductible and 30% coinsurance. Moved to Nashville and was able to get better insurance for about $200 a month. (I'm insured through an employer now, so I have no idea what it looks like post-ACA).
I had individual coverage as a freelancer for $130 per month.
I got coverage under the ACA as a freelancer for myself and my wife at $420 a month.
