Losing employer insurance, where should I look? - what worked for you?

I have 11 weeks left on my current insurance and I am comparing options. Any experience at all would help. I think my income this year might qualify for a subsidy. How fast did coverage start?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

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