What is the best and most accurate home blood pressure monitor?

Doctor says that many digital blood pressure monitors are 10-20 points below actual. Surely there's one that's more accurate.

They vary quite a bit, even between the same models! The thing is to get one and just keep an eye on trends. If your BP is high and you are being treated...just watch that its coming down.
