Good luck with that... I don't know what your definition of "good" is, but in looking around when my cobra policy ran out, there were definitely limited options, none of which came close to what most of the worker policies offered, and none covered my retina doctor. The eye injections I get would be more out of pocket than my net income right now... and after 7 months out of work, I was seriously considering jobs paying roughly half of where I'd been the past few years just to maintain a good insurance plan.
I had about 12 months of buffer, but several unplanned home and auto repairs ate into that.
