Losing employer insurance, where should I look? after 3 years as an operations analyst

I have 3 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. 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.
