Losing employer insurance, where should I look?

My family's coverage ended with the layoff and we have a prescription we cannot skip. I worked as an IT help-desk technician before this. 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 5 months ago, and it got easier once I kept a simple log of every call and form.
