Losing employer insurance, where should I look?

I have 16 weeks left on my current insurance and I am comparing options. I have read a lot of threads here and could not find my exact situation. The COBRA notice arrived with a very high price.

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.

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