What do you use to log the GPS coordinates for your photographs?

What do you use to log GPS coordinates of all your photographs??

I know some (not mine) cameras actually log GPS information into the EXIF
data but maybe we can buy/build our own with a universal GPS "tracker".

I'd be happy if I could tape onto my camera strap a small "device" that
lasted a long time on battery (a week or more would be nice) and which
logged exactly where my camera strap was.

Then I would stand a chance of figuring out at which location any
particularly interesting shot was taken by comparing the EXIF time and date
with that GPS log.

Does such a passive tiny GPS logging device exist at an affordable price
(~$300 USD or so).

I certainly don't do it with *all* my photos. Most of the time I know where
I am, and can tell same from the photo.

--however--

On road trips, when I stop at some pretty un-named spot for a few snaps, I
will take a shot of the lat/long from the car's GPS. Its not as neat as
embedding it in the EXIF (*no* idea how to do that!) but its easy enough to
track back and relate the two shots later at home.

Its fun to plug the co-ords into Google Earth (or Maps) to find out the name
of the location.

Works for me.

If I remember I'll mark a waypoint, but it's usually a case of
downloading the track and co-ordinating the times on the track with
those of the photos' EXIFs - a bit tedious, but works if I can't
remember the exact location.

I nearly always carry a small portable hiking GPS model, simply
because it's so useful for logging interesting positions regardless of
whether I'm using a camera. If I am using a camera, and it's not
possible to photograph a street name or other handy landmark, I simply
photograph the GPS display.
