We are currently on COBRA until 12/08. We pay $750/month for medical and vision. After that we'll switch to a private plan under the same company - probably for more money and less coverage.

If you have a means to get on a group plan, I think that that is the way to go. The coverage levels are so much better because the groups can get plans that individuals don't have access to.

I did some reading on the subject when we started COBRA. As long as you've had continuous coverage, there's no waiting period for pre-existing conditions such as MS. However, companies can still refuse to take you. Each time you are refused, you get "flagged" as a poor candidate; apparently the next company you apply to can see that flag in "the system". The best bet is to check into an insurance broker who knows the different insurers and can direct you to ones that will take you.

IMO, people with chronic illness should maintain their own coverage if at all possible, even if your work provides insurance. Have them both, in that case - but keep your own.
