If you are going to look at getting the subsidy by controlling taxable income, I suggest you give things another month to hopefully settle down. People have accessed the various exchanges but most are still having lots of problems. Anything you purchase won't go into effect until Jan 1, 2014 anyway. Also, you have the option of Cobra for 18 months after you terminate with megacorp. In my situation the Cobra is better coverage for the money than what is on ehealthinsurance.com. I made a few attempts at the federal exchange and it's just too screwed up.
