Losing employer insurance, where should I look? after 3 years as a bank teller

I have 3 weeks left on my current insurance and I am comparing options. There are 3 people counting on me, so I am trying to be careful. The COBRA notice arrived with a very high price. How fast did coverage start?

Compare the monthly price with the deductible. A cheap plan with a huge deductible can cost more if you need care.
