I don't want to start the great GPS receiver controversy or anything like 

Some users might find the information below helpful.  I do not claim that

My testing was not performed under scientific or controlled conditions. 
Other users could get vastly different results for any number of reasons.

I tested a Holux M-2000 and a Royaltec RBT-2110.  I tested both receivers in 
my living room and outside.

The Holux got average readings of between twenty and thirty feet.  The 
lowest was 20.8 feet.  The highest was thirty feet.

The Royaltec got readings of between fifty-five feet and ninety-four feet. 
The lowest was fifty-four feet.  The highest was ninety-six feet.

The Holux averaged eight to ten out of twelve satellites.  The Royaltec 
averaged four out of twelve.

I know the Royaltec is somewhat better at tracking direction changes.  It is 
a perfectly usable receiver in my experience.  If there is some factor I am 
not taking into account, please let me know.
