In Michigan, I had Blue Cross & they raised the rate from $130/mo to $250/mo, which is still better than the rate you have.
One thing that you should be aware of is that Ins. companies don't pay "retail". I've seen them pay a negotiated rate of 90% off the original hospital rate that I would have been charged for a procedure. So there is a hidden value to having insurance if your future company has the same practice.
And sometimes joining a Professional Organization will provide access to a discounted premium.
Thank you very much for replying and providing the info.
