Worthless click collector--a few paragraphs and much of it wrong.
Save your time.

Not to mention it's not a GSP device as spammie gave in the subject line. :)

I like these sites.
http://www.gpsreview.net/
http://www.gilsson.com/gps_reviews.htm

Bought my last GPS from http://4x4books.com/, not much on reviews but
good on price.

The links that you provided are mostly reviews and comparisons!
Not much information otherwise.

Start with "A GPS receiver calculates the exact position of a person
by using the signal strength from each satellite to narrow down the
position." Signal strength, as long as it is sufficient to allow the
signal to be deciphered, has nothing to do with position
determination. GPS works on timing, not signal strength.

"To make the readings even more accurate, a GPS receiver uses signals
from a stationary GPS receiver station. A stationary GPS receiver
station already knows its precise location, so a GPS receiver can
utilize the signals from a receiver station to correct any errors.
This technique of calculating coordinates is known as differential GPS
and almost all commercial GPS receivers available in the US come
equipped with differential GPS." While not incorrect, this is
misleading. If you buy a consumer GPS it will have support for DGPS
but you'll also need to be within range of a transmitting station and
have a DGPS receiver compatible with that service, which is a separate
device that plugs into the GPS. There is no mention of WAAS, which
most commercially available GPS units support and which provides
accuracy close to that of DGPS with a single satellite providing the
corrections.

The only manufacturer mentioned is Garmin--no mention of Magellan,
Trimble, or any of the other manufacturers.

The wikipedia article contains a great deal more information.

Indeed.
Besides http://en.wikipedia.org/wiki/GPS
which for some reason escaped me at the time.
