COBRA quote is huge, any alternatives?

The COBRA quote for my family is $600 a month and I do not know how to afford it. I worked as a bookkeeper before this. I saw that marketplace plans might cost less. How did you decide?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.

A quick call to the plan's member line cleared up two things for us that the letter did not.
