I'm already on Medicare but my wife is a few years younger. Her premium in NJ under United Healthcare--Oxford went from $429/month to $1125, with a much higher deductible. The good news is that she is covered for pregnancy at 64. Probably covered for prostate cancer as well.
We checked into some alternatives and found Liberty HealthShare. I strongly urge anyone interested in saving a fortune in healthcare costs to check it out.
