There are good threads at Balloon-Juice on medical insurance.
David Anderson is the front pager there that talks about it clearly and with lots of facts. Lots of good comments on his threads. One woman makes the point that if you're in an Advantage plan, there are severe constraints if you later decide that regular Medicare works better.
E.g.
this comment by Ohio Mom.
Personally, I start suspicious when for-profit outfits advertise insurance on TV. TV ads cost money, and that money has to come from somewhere... So, while Medicare Advantage may work, one has to verify it with one's own work based on one's own circumstances.
We're a few years away from signing up for Medicare, but we dread the process.
David makes the point that picking insurance is complicated and there are too many variables to make an "optimum" choice. The best you can hope for is to not make a bad choice, and keep an eye on annual changes.
Good luck!!
Cheers,
Scott.
