There is a VERY tiny, economical GPS that isn't much larger than the
antenna called a Deluo. I got a pair of them for $xx each (plus shipping).
The serial port version (there's also a USB version) has a female DB-9 and
a mini-DIN connector at the end of the "Y" cable that comes out of the
unit.
The cable ends are molded on, and I haven't had the "cojones" to try and
trim excess length and replace any connectors, yet.
It needs 5 volts DC to power the GPS. 12 volts will smoke it.
So far I haven't figured out how to tell it to suppress unneeded NMEA
strings, so in addition to the $GPGGA and $GPRMC it spews a bunch of
others, but the TinyTrak2 didn't seem to have a problem with it.
Not sure about the current draw, yet - but suspect a 7805 should handle it
fine. Be sure and acquire the pinout of the PS/2 mouse and keyboard ports
(a published standard) to build the power supply unless you want to cut off
the connector and wire your own.
Performance wise, plugged into a notebook and drawing power from its PS/2
connector, the unit seemed to acquire a good fix faster than the Garmin
GPS-35 in difficult conditions (trees, buildings).

Nice band opening right now over the central states... I'm seeing stations
in Iowa, Nebraska, Minnesota...

I have successfully used my Garmin EMap for quite some time connected to
my D700. The nice thing about the Emap is it has the largest screen for
a GPS of its size and price point. Sure you could go with a Street
pilot for MUCH more money and get a larger color screen, but I don't
really need that. I think the Etrex's will also work, but their screen
is much smaller than an Emap.
Just my .02 worth!
