Losing employer insurance, where should I look? (Nashville)

I have 3 weeks left on my current insurance and I am comparing options. I am in Nashville, in case local advice matters. I think my income this year might qualify for a subsidy. What did you choose and how was the process?

Thanks for writing this out. I went through something close to it 2 months ago, and it got easier once I kept a simple log of every call and form.

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