Those of you that are between jobs, stuck in internships, etc, check out ehealthinsurance.com it's like expedia for insurance plans. Offers all sorts of plans in all sorts of price ranges. You put in what you're looking for and it gives you options and sends the forms in to the insurance companies for you. I used it to buy a plan when I was between jobs and before I started grad school. WAY cheaper than COBRA.
Whoever mentioned catastrophic, it's always good to have some sort of coverage but be careful because many of those plans specifically list skiing injuries as non-covered.
