I went shopping yesterday. My doctor and hospital group aren't accepting any individual plans issued by any insurer, so I'm really just buying a plan to cover emergencies. In that case, they have to treat me and accept my insurance unless they can find a place to send me outside their network.
This year I've been paying $816 a month with a $6,000 deductible. The closest I could come is a plan that will cost me $996 a month and a seven grand deductible.
So in my case, 2018 will be neither better or cheaper.
For what it's worth, I just pay cash for my doctor visits and get a big discount. It's one way to keep your doctor, insurance just doesn't pay for it.
Those of you on company plans don't know how good you've got it.
