Losing employer insurance, where should I look? (St. Louis)

My employer coverage ended at the end of the month and I am trying to work out what to do as an accounts payable clerk. There are 3 people counting on me, so I am trying to be careful. The COBRA notice arrived with a very high price. What did you choose and how was the process?

A free navigator at a community health centre walked me through my options. It took an hour and saved me a lot of guessing.

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.
