It will take a while, but I expect to see the ublox NEO-7 chip become available to experimenters on small printed circuit boards with integrated patch antennas and support components in the price range of $50 to $100. A GNSS receiver built around this chip would allow position finding with accuracy of 3-feet or less. The chip is also able to support DGPS, if one were able to find and incorporate a DGPS receiver. This is the latest generation of chips from ublox.
The prior generation ublox chips like the NEO-6 were GPS-only receivers. They are selling now for about $25 to $50 when integrated on small circuit boards, such as this one intended for use with the popular Arduino stack:
And this one, for $22:

At this moment it looks like the ublox NEO-7N is selling for about $40 for just the chip alone. The just-announced NEO-7P precision GNSS receiver is probably going to be more expensive due to the added precision of its receiver.
The prospect of a marine GPS with sub-meter accuracy is not too far away, based on this new chip from ublox. Exactly what the cost will be when this device is provided in a marine form factor is hard to predict, but it most likely will be quite a bit more than the cost of the experimenter boards mentioned above.
