Basically, Obamacare is a ripoff for healthy and young people. The logic is, take as much money from healthy people and use it to pay for the sick and old. For people having poor health ondition, this might be a good option.

Depending on your state, price may be different, but on average we will end up paying $250-$300/month for Silver package. They have more expensive Gold and less expensive Bronze package as well. Right now we can get Silver package equivalent insurance for around $60.
In short, we have to pay $200/month extra for Obamacare. For low income (<46k/year) you might qualify for low payment.
