COBRA quote is huge, any alternatives? after 13 years as a data-entry clerk

I was offered COBRA and the monthly cost is more than I expected as a data-entry clerk. There are 13 people counting on me, so I am trying to be careful. I saw that marketplace plans might cost less. How did you decide?

If you have a planned treatment, COBRA can make sense for a few months. Otherwise look at the marketplace first.
