Losing employer insurance, where should I look?, insurance claims processor here

I have 3 weeks left on my current insurance and I am comparing options. I am in Cincinnati, in case local advice matters. The COBRA notice arrived with a very high price. How fast did coverage start?

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.
