Losing employer insurance, where should I look? - 17 weeks in

I have 7 weeks left on my current insurance and I am comparing options. I am in Columbus, in case local advice matters. I do not want a gap in coverage. 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.
