Losing employer insurance, where should I look? - any advice?

My employer coverage ended at the end of the month and I am trying to work out what to do as a bookkeeper. It has been weighing on me all week. I think my income this year might qualify for a subsidy. What did you choose and how was the process?

Losing job-based coverage usually opens a special enrolment window, so check the deadline on the official marketplace site. I missed it by a day once and regretted it.
